GOD BLESS THE B.B.B !!!
I experienced an Intermittant Multiple Cylinder Mis-fire that occured abruptly and continued until I replaced the exhaust valve cam position sensor. I performed this repair based on a OBDll code and chose to replace it since the other referenced sensors were not available at the local parts store. I immediately started the truck after replacement and had no further issues. The next morning I drove the truck about 5 miles and the same exact syptoms occured again. I parked the vehicle for about 20 minutes while I went into the store, came out and it ran perfectly fine since. I have noticed though that the power doors locks do not function and the drivers window is inop. Any ideas? I have reviewed the blogs posted and have noticed a number of discussion on the GM Cylinder Head issue , though have a hard time believing it could be the same. I also believe there is a GM issue for the door locks and window though have not seen anything.
:mad: :confuse: :lemon:
The radio stays on even after I remove my key and shut the door, but it will turn off sometimes when the passenger door is opened and closed.
I was thinking maybe a ground issue? All of the fuses check out good. Any Ideas??
Thanks
Pete
Anyone had this problem and got it fixed?
Thanks Gary
i got the same problem
First the air bag light came on
after i scan the problem the scan said :open circuit on belt tensionnner (code 0446)
i remove the rear door panel and i check the circuit on the tensionner and at the same time i didn't, hear any sound on my rear door speaker,i check every thing and no sound ok , i check the light switch on bottom the rear door (switch for the dome light) nothing work . there 6 wires on this harness ,5 of them were broke on the at the flex point.
I m a automotive tech for one of the biggest industries in Canada

i work with Ford, Gm Chrysler, Kenworth peterbilt International truck John deere Cat etc etc and when i call the enginering at GM
he told me Gm know about this problem, and you have to write to GM complaint departement, in other word do the repair and wait
hope these information help you

you see an ovale connector with 4 wire on
disconnect the connector and check the third connector must be burn
small wire terminal is stock on GM dealer
Second: on the heater housing (where the connector was placed) you have a think call blower resistor remove the 2 screw (one each side ) and check if the any resistor (curl wire ) broke or in the resistor you got a diode (must be blow)
if there one those thing broke , change the resistor aroud 15.00 $ /auto part
or 45.00$ GM dealer
hope everything help you

Check on your Rear driver side door ther is a rubber tube where the wire pass trouw
wire must be cut inside
check all wire
remove your rear door panel and remove one clip (one who hold the harness)
when you open the door wire inside is to short and broke
there 6 wire check them all 2 for the door switch
2 for speakers and two other for belt tensionner
if this one is broke air bag goes on
hope that help ypu
Jean
if you have missfire or bad idle
there is a problem with valve seat
Gm replaced the head and job at no charge
check at any Gm sevice

Just a thought, The mechanic spoke as an expert, without knowledge on this subject??? Try another mechanic!! :surprise:
you may write to the wrong member
i spoke about the wire cut on rear door (ext cab) the belt trigger wire was cut on rubber cover (open circuit on belt tensionner )air bag light on
second im not an expert like you said , but the air bag device need decelleration in an amount of time
bettwen 0.4 to 4.0 G in less than 0.65 second
i got a driver driving a Chevrolet silverado 2500 4x4 2007 who lost control on a gravel road at 70MPH
hit a rock, lost the front right suspention and tire goes off , jump 15 feet in the air and finish is ride on pine tree. The front frame was bed 5 inch to the right, the rear differential goes off the center pin, the rear frame was bend enough, the rear box broke the rear glass NO air bag deploy ,you know why
the GM tech came at your shop an scan the ecm
answer : not enough deceleration in time required
You talk about force i think there enough force there to bent the truck but not enough to deploy the air bag
Thanks

Totaled over $800 in repairs over 2 months. They covered nothing but the fuse block. Good business sense there... I will never buy another Chevy product.
If you are referring to buying one of those what are you going to do when you have a problem with your new Japanese car/truck? Look at their forum they have issues as well.
You will have Hyundai, Volvo, BMW, and a few other brands left if you keep abandoning brands.
I also complained to the manager about this problem that this was a mfgr. material defect or a workmanship problem because I faithfully had my truck serviced every 3 months and only had 15,046 miles on my odometer and no reason to do anything under the seat, plus the warranty had expired 2 months prior.
The manager called back 2 hrs. later and said they will not charge for the repair after talking to customer service at GM Headquarters. Thank Goodness
everyone has problems! Also, tacoma and frontier is out selling like crazy compare to colorado and canyon
1. Both key fobs will lock the doors but not unlock them.
2. The inside switch locks and unlocks the doors just fine.
3. When the key fob unlock button is pressed, the lights blink like it is going to unlock the doors but they don't unlock.
4. When you remove the key from the ignition, it does not unlock the doors like it used to.
5. If you use the key to unlock the doors without first pressing the unlock button on the key fob then the horn starts beeping. You have to press the unlock button then use the key.
6. All other electrical functions are normal - lights, windows, etc.
What do you think? BCM? If so, is there a way to check it and/or repair it? Anyone have a schematic of the beast or for that matter, a wiring diagram that's better than my Hayne's manual wiring diagram ( sucks ). How does the dealer check problems like this being that it's not throwing any codes on my code reader?
On the 'Vette, this board is in a plastic housing behind the door panel. Thanks to a member of the Corvette web site, I was able to repair the circuit board for under $5. (Well, actually it cost me a little more, because I had to purchase a de-soldering tool)
I'm not positive but I think those relays that you are talking about might be in the switch assembly in the door panel on the Colorado. I'll remove the switch assembly tonight and disassemble it to see.
I'll post my finding here.
Cheers.

I pulled the connectors loose on the BCM hoping that it might 'reset' it but it had no effect.
I sure hate to take it to the dealer but I can't afford to just change out expensive parts on a whim and I can't find a decent schematic.
I tell you why the truck costs so much - there's $15,000 in wire in the thing. When you start looking behind covers and things it's amazing how much wire and how many connectors there are!
Cheers
It could have been helpful.....
For anyone that is having a problem where both your door lock button as well as your key fob doesn't work then I'd look at the relay as a probable problem. The relays on the Colorado are smaller than the ones on the Vette but they are replaceable.
Unfortunately, my problem was that only the key fobs wouldn't unlock the door... the switch still worked which means the relays are good.
When I figure my problem out I'll announce it here.
Cheers.
To the best of my knowledge, you turn the key to the "on" position, then hold the lock and unlock buttons on the fob simultaneously for a few seconds, or something like that.
