Chevy Silverado: Problems & Solutions

lost4

I have heard that the allison transmissions in the Duramax 2500 have problems. Can anyone inform me if the 2005 model has this problem.

I just purchased at 2000 Chevrolet Silverado 2 x 4 and the switch controling the air flow.
(#1, 2, 3, 4, and 5) in in tact but, the Number 1 positon does not work.
The rest of the numbered items each work and blow air. I went to a wrecking yard and replaced the control unit thinking that maybe the #1 position was bad. Same results with the new unit. Maybe I should look at the heater motor. I think it is encased under the glove compartment on the passenger side of the truck.

I removed the ash tray and pushed up a snap out unit that is around a small round item and need advice on how to get the snap outs back in place.

I have a 2005 chevy silverado 2500 HD and it has whining noise coming from the transmission . The dealer replaced a whole bunch of parts in the trans and still with the same noise and is getting louder . The mileage on the truck is only 6000 .

Anyone have a copy of a wire diagram for a steering column for a 2002 Silverado 2500 Duramax or is there a reset for the electrical system. Had a short in the headlights wiring but now the truck won't start! :mad:

You need to replace a diode in the unit. Those are famous for failing thus losing control of air flow via the switches. Think they are under a dollar at Radio Shack. Going to need a soldering iron too.

Interesting, I have just recenty experience the same thing. I have 24,000 miles on a 2003 Silverado and my ABS motor underneath the vehicle is making noise. The only way to stop it is to take out the ABS fuse in the engine compartment. Quality at its best. Any ideas before I take it to the dealer?

Hi, I have the same problem, I think. I have a 2005 Chevy Silverado which has a rough idle like you described for your truck. The first weekend I had the truck, I went out to the truck to run an errand and it would not start. My stepson got under the truck and hit the bottom of the gas tank and the truck started. I took the truck back to the dealer to get it checked out.
The dealer stated no codes came up, every think is running per spec's. The engine still runs rough, it runs fair some days and some days the engine runs very rough. The truck has been back to the dealer twice for rough idle. Their opinion is no engine light no problem. The service manager did say he thought a reprograming bulletin will probably come out for this issue in the future. You know its a shame you spend a lot of money on what you think is a good truck and they can't even address the idle.
If any body has any thoughts or comments I would welcome them
Thanks

I have a 1999 Chevy Silverado with daytime running lights. There rather annoying when pulling into a parking lot and park and wait for someone to come out and you cant turn them off unless you turn your truck off and put the parking brake on and then restart it. My moms blazer 2000 the Dome Override button lets you override the headlights to at night so you can turn them off. Which i want for my 99 silverado. Isnt there someway to wire a 2000 silverados module to my 99 silverado or something? I push the button and all i get is interior dome going off and on.

i have a 98 chevy silverado 4 wheel drive. after about 35,000 miles on the truck the steering wheel will jerk to the left very quickly and then steer fine for a week or so and do it again. it happens a slow or highway speeds. has anyone had or heard of this problem?

medic159

My 98 silverado shifts VERY hard when it gets hot. Particularly after interstate driving. Once it cools for a short time it is fine again. Can anyone help? The truck has 5.7 liter and is extended cab 4x4.

I have a 1992 C1500 with a 350 ci engine. It seems to be burning oil. About a quart every 400-600 miles. I only notice smoke coming out of the exhaust every now and then. I will hear a slight rattle sound and then a puff of whitish smoke will come out of the exhaust. Someone told me it was "Blow by" in the engine. What can I do about this. I have, at the recommendation of the guy at the parts store, tried Lucas in the engine. I check my oil at every fill up and have switched to a thicker oil, 10-40.

I just bought a used 2003 2500hd ls and the horn didn't work along with the tow light on the dash. Does anyone know how to fix the lights on the dash? I got the horn to work by pulling out the fuse and putting a new one in. I can't find anything in the manual for the tow light. I also am unsure if the 4x4 light on the dash is supposed to come on. I change the 4x4 button from 2 wheel to 4 wheel but the dash light doesn't come on. Let me know if anyone knows how to fix this problem.........

MR................
Best bet is to pull the bulbs.

Your truck SHOULD have a seperate 10 amp
DRL fuse in the underhood fuse center. Check for it.......................

I own a 91 2500 4wd and the air from the vents is always hot. The electronic heater/ a/c gauges will advance and the air flow can be regulated from the floor to the dash. Is this a problem with the thermostat, vacumn lines, low freon, or something else? I would be happy with no hot air blowing constantly which adds to the 100+ temps In Texas. Thanks in advance!!!

I noticed at 6,000 miles that my fromt tires were chopped. The dealer told me that the front end allignment was off. I also noticed this problem with other 1500 HD Silverado Trucks. I had them replace both tires and correct the problem. I was told that if you don't catch this problem before 12,000 miles, that it becomes your problem. I have the dealer do all my services and I was surprised that they didn't catch the problem at the 3,000 mile oil change.
Note: Look at your Bridgestone tire warranty booklet. The dealed has to sign off that they checked your tires as required by Firestone or you will loose any warranty.

I have a 2000 Z71 with a 5.3 and not too long ago i got a service engine light about the knock sensor but before i replaced it the light went off and i still hadn't replaced it. Now it is misfiring when i try to accelerate not all the time just when accelerating. I am also getting a misfire in cylinder 2 code so i changed the plugs to AC Delco performance plugs, and replaced the $70 plug in cylinder 2. Does anyone know what might be causing these problems?

medic159

I have a 98 silverado with a 5.7 that did the same thing. I found a small hole in the rotor button that was causing the spark to ground when i accelerated. changed the button and runs fine.

I have a used (2000) duramax diesel. with allison trany. I got this truck in feb of 2005 and since the hot weather has been here I have had a problem with the trany.
when the trany temp goes up to say 105C (in think) which is quite hot but not really hot. (not in red).
here is where it gets a little confusing. once hot and if i go from forward to reverse and then back to forward, once i accelerate the trany will slip for a moment and then the engine will rev up and then the trany will slam in to gear and start to move the truck but the RPM is above where it would be it the truck was cool. This hi reving will occure till the truck cools. then all is ok till the truck gets hot again. this is an intermitent proble only when the trany temp gets up to high. i get an engine light will come on and will stay till truck cools. once cool light goes out and all is fine.
The previous owner had truck in several times for this problem but obviously was never fixed. Any one know what is going on and what should i do.

I have a 2002 2500HD. The owners manual says to use TH mode when the weight of the truck and the tow vehicle is at least 75% of the CVWR. The Allison Transmission FAQ site says to use TH mode whenever you are towing. Which is correct? I haul a car trailer. With contents it weighs 6,000 lbs. so I am way below the 75% CVWR as I carry nothing in the bed of my pickup.

rayt2

My experience has shown for best results when hauling or towing anything of weight to use tow haul mode. Also leave trans in 3rd gear, do not use overdrive. Leaving in overdrive will cause more "hunting" by tranny especially when going up grades.
I tow a 28' travel trailer w/gvw of 6600#s
Hope that helps.

97 chevy 2500 4x4 automatic with ABS. Last year in parking lot, turned key on and only accessories would turn on but truck wouldn't start. Could not hear fuel pump. Had it towed and dealer said it was bad fuel pump, the wires were burnt. I asked how that can be when the fuses are meant to protect the wiring from doing just that.. said "I don't know.".. 2 weeks later same thing happened.. towed back and they claimed it was the sender unit.

Ok.. So now year later.. truck acted same way.. Could also hear strange buzzing noise coming from under the dash.. by the fuses perhaps.. but this time I disconnected the positive battery cable and waited a while. Reconnected and truck started right up. Couple weeks later truck started right up but would not shift into gear no matter what I did. Fiddling while stepping on the brakes as hard as I could would not allow it to shift.. Disconnected battery on a hunch.. waited.. reconnected.. truck started right up and would shift into gear fine.

In addition to these problems I would notice the oil, gas gauges bouncing around.. like it gets a sudden jolt of charge.

Nobody has any clue what this could be.. have given up a dealer since they don't wish to help. Any ideas? Help!

:confuse:

Has anyone had a problem with the little motor under the steering column next to the fire wall. it runs back and forth making an annoying noise. I was wondering what the heck it is and how to get it to stop.

noobie1

What the heck is a steering sleeve? and where is it located?

mt_hunter

The tow/haul light on my dash doesn't come on whn I hit the button on the shifter. Does anyone have a suggestion on how to fix this myself? I looked through the scematics on wiggled some fuses but they didn't fix anything but my horn problem. This is driving me crazy!!!!!!!

dave93

sounds like a broke stabilizer link or bad cv joint

jon_lo

I had this same problem. Its caused by release latch pivot pin rusting. I removed the release latch, remove the two screws on the inside of the tail gate. Take care not to break the plastic clips that hold the pull rods that go to the latches. Drill out the center pivot pin but be carefull not to destroy the Nylon washer. Clean off the rust and apply a heavy amount of silver never-sieze and then re-assemble with a sholder bolt. I did this about 3 years ago and has worked great ever since.

i have a 92 c1500 2wd with a 350 V8 and my guages let me know every time something is using battery power by moving incluiding my speedometer which spasms when i put on my blinker, i suspected a ground wire may be the problem but im not too sharp with electrical stuff

lhess

in the last couple of month's, we have noticed this ticking noise (almost sounds like a steady drip of water) while inside the truck. Seems loudest from the passenger's side just behind and below the glove compartment. It does this while the truck is running and after shut-down. When we fueled up yesterday, this ticking went on (with the truck shut off) for well over 15 minutes and continued when the truck was running and back on the road? Any ideas? We're planning to take it to the dealer, but those poor folks seem to be clueless and I would like to have some idea of what it is.

rayt2

Dave, Check the ground cable that goes from engine to firewall, remake the connection as well as battery connection.. I'm guessing but a bad ground can cause electrical flucuations.

Ray T. :shades:

rayt2

Sounds like a possible heater core leak within the plastic housing under the dash. Check the underside of the plastic housing for wetness. Check water level in radiator overflow canister, is it low? Check your passenger side floor underneath the carpet and insulation for wetness.
Hope this helped somewhat........

I pulled the abs fuse out of the fuse block in the dash board to disable the abs on my 2001 Silverado and filed a complaint with the National Highway Traffic Safety Administration.

A recall order was issued on Aug 29th for the problem of unwanted ABS activation on 1999 thru 2002 Chevy Avalanche, Silverado, Suburban, & Tahoe models and GMC Sierra, Yukon & Yukon XL models. NHTSA campaign number 05V-379. Possibility of 804,000 vehicles affected. Owners should call Chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.

grogers

Can you tell me if you found out what is causing this? I am having the same exact problem right now. The fuse is fine until I put the truck in gear and then it blows. If you can give me any info that you got I would be very thankful.

teener

Help! I have a 95 Chevrolet Silvardo ext cab 2wd p/u. Have lost low beams but my high beams work. Have checked the fuses, have tried to replace the composite bulb, still no low beams. Any suggestions and what price range I'm probably looking at to get fixed?

I have a standard transmission 2005 silverado. It makes to much noise in the transmission to drive. GM says that this is normal for a chevy. I have took the truck to 2 dealers only to have one person tell something is wrong then another tell me this is normal on repeated occasions. When one says that it needs repaired when i return for the repair another will tell me this is normal for a chevy transmission. I would like to know if anyone else is having problems. There is a memo from Gm headquarters that says that any bumping, banging, knocking or growling is completely normal for this transmission. How then would you know if something is really wrong. It sounds like the pilot bearing has been left out. I have been unable to get them to even put the truck on the rack to look at it. If anyone else is having similar problems please let me know. I don't feel i can safely drive the vehicle so i have returned to driving my old one with the new one setting in the yard.

oldbscaler

I have the same truck a 2002 2500 HD with a 8.1 and an Allison Transmission. I just started experiencing the same problem. A few weeks ago I noticed a quick flash of the battery light and would notice the door locks (I think) click. Then all was fine. Last week it started to quit just the way you described. Have you found a fix? Any ideas?
Thanks

lhess

will check that out!!

I guess by now you have realized that your ABS system is shot. Chevy will glady fix it (you cannot buy a kit or install yourself) for 999.00 (price in Florida).

blacktruck1

I was wondering if you found a solution.

I just purchased a 2000 Silverado with a 5.3L and when I first test drove it, it apparently had a problem misfiring (hindsite) and the service light came on, I told the dealer I wasn't interest but if they fixed the problem to call me. A week later they called and said they fixed the problem. I saw the paper work from the Chevy dealer that fixed it and they replaced the fuel pump and drained the take. They told me it was bad gas. I retest drove it and it ran fine. I bought it (no warranty) and a few days went by. It started again. I filled up the take and it seemed to fix the problem. A couple of miles later it started again. I checked the codes and I got a reading of P0303 (cyl 3 misfire). I have since changed the plugs, swapped coil and wires with no avail. I am now being told from my backyard mechanic friends to replace the camshaft & crankshaft sensors. This could start to get expensive grasping at straws. I was hoping you might have found the problem...?

creaseguard

I've got the same issue with the ABS/Brake light in the same model and year truck as you. Did you find out what was causing this problem?

tcowgirl08

I have a 2004 silverado HD with a standard trasmission. Since day 1, my clutch & transmission has made terrible noises. The dealership has finally made repairs to the transmission (for which they originally told me were "normal"), now I cannot get rid of the noise the clutch makes when I depress it?! I have taken it to a transmission shop in town, he cannot find what the problem is...but states it is "not normal", & the dealership needs to fix it since it is still under warranty. The dealership will not replace any more parts until GM discovers a new way to fix the problem. In the meantime, it is STILL not fixed?! I don't know what else to do! They are not concerned, because they are not the ones driving it. I'm not sure if there is more to this problem than just the noise, & would like to know if anyone out there is having any similar problems with this vehicle. I wish I had another vehicle to drive until this one is fixed! ">

I have a 2001 Chevy 1500 and the other day I was on a road trip and stopped for gas, all was fine until I had been driving for about 30-40 miles after getting gas, and I was going about 70mph and my truck died in the middle of the highway. I eased my way to the side of the road and over to a gas station and when I put the truck in neutral it acted like it was still in gear and died. So then I nursed it back home and the whole time if I had to stop or downshift it would stall and make loud clanking noises. It was also smelling very bad maybe like if it was burning oil. It has just over 100k. If anyone can help it would be great.

rayt2

1999 thru 2001 just announced on CBS news the other night more info to follow from GM to owners of the 900,000 affected trucks.

Call GM customer support and log your issue. Then take it to another dealer.

dmilacek

There is a guy (Galvin Curtis) that will fix it for $100 if you take it off and send it to him. That is if you pulled the fuse before the ABS module ran too long. I think his business is Circuit Solutions. If you are interested, I think I can find his email address.

Okay, this is a long one… My 2001, 8.1L 4X4 started with a problem of cutting off. Sometimes while idling and sometimes while driving down the road! It’s almost like someone reached over and turned the ignition off! Sometimes it would start right back up; others times it would crank for a few minutes until she felt like starting. Then, I’d go on my merry way like nothing ever happened. This has gone on for two years with months in between episodes. However, lately, it has happened much more frequently and this past weekend would only idle for 3-5 minutes before she’d cut off. In addition, the “Service Engine” light and even the “Reduce Engine Power” light in the message center has come on, at the same time. Any thoughts?

Since you have an SES light get a hold of a scanner (free use at AutoZone) and find out what
DTC('s) has registered. Go from there.

FYI - Check out Post # 449 and follow the reply links. And stay tuned here; You might get clues from someone who solves their problem.

fatman97

Yeah I have this problem, and that is how I got to this site. I do not have a solution just yet

towcray

Thanks David. I can see that a number of folks have what seems like a similar problem but I can't for the life of me find where anyone's figured it out yet. I'll keep looking and thanks for the advice.

Any one out there have problems when its over 85-90 deg? My 05 with 36k on it will not make air colder than 60-65 deg when stopped. Going down the road its a little bit better 55-60 deg. Dealer says its "within Specs". The airflow seems low as well. With recirc selected there is no apparent change in airflow.
Thanks,
