Chevy Silverado and GMC Sierra General Operational Questions

    I just bought a 2008 Silverado. I would like to program the automatic door locks so they do not automatically lock, but the best my dealer could do is get them to lock when I have been going 8mph for 3 seconds and unlock when I put it in park. In my 2004 trade in I was able to disarm them. Is it possible to turn them off? Thanks for any help you can give me to this annoying problem!!

    Sorry Korn.................yer outta luck!
    GM and the feds gave us another "nanny" to save us from ourselves !
    From 2005 and up you can only set the auto locks to either lock when
    put in gear or at 10 mph. NO more shutting them off like our 04s did !

    Heres other gem "nannies" we now have with out GMT-900s:

    No more turning off the door/key-in/seatbelt chime warning !
    All you can do is have it either sound off loud or soft.............
    Or throw away your stock radio for a aftermarket unit. The chime has
    been generated thru the radio since 03 or 05 I believe.
    My 01 had a seperate chime unit I just unpluged!
    But Crutchfield audio DOES sell a module to enable a aftermarket radio
    to produce warning chimes! Must sell a lot of them ya think?

    Another is the wonderful Tire pressure monitoring system (TPMS).
    Mine has been going haywire since new. First it was just a warning light.
    After being ignored now it won't show any tire pressures and I get multi
    service lights and a chime!
    I think my truck wants to mate with the dealers Tech 2 machine !!!!!!!!!!!!!!!!

    My 03 Caddys TPMS ain't made a peep since new !

    Nice truck tho..........No other issues and I work it hard snowplowing or
    heavy towing!................... :P

    I don't know about the fed law. Some other brand of trucks can have the door locks turned off completely & the passenger side seat belt chimes can be turned off but the light still flashes. Maybe your dealers telling you that like gm dealers do.Don't Know But I do know gm dealers lie.
  • obyoneobyone Posts: 8,065
    So what exactly is your point? That you don't know federal law? or that some other truck's chime can maybe be turned off? That dealers lie?

    I would think the best bit of advice would be to read the owner's manual? Make sense to you?
  • mule4mule4 Posts: 36
    The post should speak for itself. I don't know if there is a law or not . But other brands of trucks can be changed.So why can't gm.if others can do it. About beinging lied to check out other gm post about some of their experiences. beinging told their problems are normal.I know i've been lied to alot of times.about the gm cars & trucks i've owned.But it won't happen again
  • obyoneobyone Posts: 8,065
    Being lied to isn't brand specific rather dealer specific. On any given day you could go to any dealership and get lied to and it could be just that they are too busy to care. I don't see how your post helps the original poster cause all you're saying is that all GM dealers lie, right?

    I remember all those Toyota owners being lied to and being called liars when they tried to get relief for their sludged vehicles. But that is way too off topic.
  • mule4mule4 Posts: 36
    I'm saying why don't gm change the settings if other brands can.Most people don't like their doors to lock when working in & out of their trucks.Or seat belt chimes going off when moving a few feet.A flashing light should be enought.The man should change dealers. He might get it changed.

    Not to be a wise A--,but when i bought my 3 trucks i bought them for what i thought a truck was supposed to be,to haul. Mine didn't have all the creature feature toys to go wrong, and have to pay mucho bucks for. IMHO,its time to get back to basics.
    O.K,now start the flaming. ;)
  • obyoneobyone Posts: 8,065
    After the psychiatrists invented Attention Deficit Disorder, the truck manufacturers with the help of their attorneys developed all these fail safes to protect the owners. Because of all these additional features, back in 2003 GM decides to do away with the cabin air filter on their trucks which IMO thought was one of the better features with all the air pollution. But I digress, and will not buy another GM truck because of the lack of a cabin air filter.
  • I have an 08 Sierra SL and want to add the driver information center buttons so I can change lock options, see fuel economy, etc. I see the panel is available from GM accessories but is it plug and play or does it require dealer programming to make it work. I know some of the info is there. When Onstar emails me a diagnostic it shows individual tire pressure but I only have the idiot light without the buttons. Has anyone added this option or know what is involved. I called the dealer but they didn't have a clue that this was even available as an accessory so they really didn't know what it entailed.
  • obyoneobyone Posts: 8,065
    DIC is a plug and play feature. There is a post on here about it. What it entails is buying the DIC, removing what's there and plug in the unit. No programming needed by the dealer. Think the part was something like $100.

    It is easy and many have done it especially those with the W/T trucks. I'll post the link if I can find it.

    Found it.

    DIC upgrade
  • Thanks for the info. That is what I hoped to hear.
  • obyoneobyone Posts: 8,065
    Hey mule maybe you could help hdfatboy over at the Toyota Sequoia forum. Apparently he was told by the Toyota dealer that there is a Daytime Driving Light switch which will disable the DRL located on the stalk with the regular light controls. He says he can't find it but on the Moroney sticker Toyota charges him $40 for that DRL switch. Dealer tells him he has to have it if it's on the sticker but he still can't find it. Those lying Toyota dealers eh?

    Back to topic. One wonders why GM cuts costs in the areas they do. The DIC is a $100 and I would think the information it provides is well worth the price. Guess the bean counters at GM think differently.

    my truck will start on a nice day, but when there is alot of moisture it wont start or if it does it jerks and acts like its starving for fuel. i had a tuneup took it back 2x
    they told me i hadbad wires or cap, i thought they fixed it but ??? i was going to buy a fuel pump, but i don't know if thats the problem..
  • mac53mac53 Posts: 2
    I have a 2000 GMC 4WD with ABS. When coming to a slow stop, the ABS kicks on and stays on until I pump the brakes. It doesn't do this on hard stops. It seems to be especially bad when parking in a parking lot. Anybody else had a problem with this?

    The fuel tank capacity of my 2008 Chevy Silverado 2500HD (diesel) is specified as 26 gallons. When I run to empty (~20 miles indicated on the computer range function) and fill the tank, it only holds 20 gallons.

    I assumed a sensor/sender was out of calibration but my dealer says that Chevy designed it to have a six gallon "reserve". I can't believe that they would use almost 25% of your tanks capacity for a reserve that is hardly going to be used.

    Should I run my truck 100+ miles past empty and see if my mechanic is telling the truth?
    My search of this forum didn't show any discussion of this. Has anyone else seen this before?
    Thanks, Mike
  • obyoneobyone Posts: 8,065
    This is nothing new. GM has done this since 1999. I have personally noticed this on Dodge, Ford and Toyota trucks all with fuel reserves of approximately 6-7 gallons to idiot proof refueling as some run longer than normal and do run out of gas.

    Was question #17 answered? Sorry, new user
  • efunk_76efunk_76 Posts: 2
    My 2000 silverado ignition won't turn when key is put in to start. Is it my security system that has locked i?
  • obyoneobyone Posts: 8,065
    No it wasn't.
  • obyoneobyone Posts: 8,065
    I have that same problem on my '02 Denali. Not sure if its the steering or the security. Moving the steering wheel around eventually gets it started and since its really intermittent haven't done anything about it.
  • Dan it could be the gas your buying, my wife's Cadillac does the same thing, but when she stopped putting the alcohol blend in her tank and went back to regular premium her problems went away. I don't believe the grain fuels are the answer for gasoline, Diesel maybe

    My gas gauge keeps going to 0 then back up to showing proper reading. I saw a forum discussing something about the connector? The truck just turned 100,000 and I've had it since new. It has had a couple occasions when all the dash lights came on at start up and idled poorly with the console lighting fading in and out. Also it hasn't started a couple times, but started after sitting a couple minutes. Repair shop can't find a reason. When I mentioned the gas gauge to the dealer they said they'ld check into it, which sounded kind of strange to me!
  • does anyone know if i can pass the smog test with my check engine light on? it is just on because my fuel sending unit needs replaced so i figure that has nothing to do with smog so it should pass. thank you
  • I purchased a used '05 Silverado 1500 a few months ago and now that winter's here I tried to use the heated seats. I thought they worked when I bought the truck, but apparently not. Does anyone know how or know where to go for information about troubleshooting the heated seats and/or replacing the heating pad in the seats?
  • obyoneobyone Posts: 8,065
    Have you checked the fuse or the switch?
  • Not directly. I don't suspect the switch or the fuse. The seat back heat works and the lower cushion does not. I only found one fuse listing "Heated Seats" so I suspect that all four heaters (2 driver and 2 passenger) are power via the same fuse. The switch appears to be a low voltage system (not direct drive to power the the seat heaters) as this model has three levels of heat. Each time I press the switch the heat level changes (off-high-medium-low-off-high- etc.).

    Right now the most likely suspects in my book are the heat controller or the heating pad itself. But I can't quite figure out how to get it all apart. I purchased (ie., wasted my money) the Haynes manual. It has nothing about heated seats in it.
  • obyoneobyone Posts: 8,065
    The power for the heated seats comes directly from the battery via a 30 amp fuse located under the hood. I would agree that this is not the problem and it's either the heat element or connector.

    There is an 18 step diagnostic to trouble shoot this problem. If you plan to work on this truck on your own I would suggest buying one of the following manuals:

    Helm factory manual

    Ebay

    http://www.alldatadiy.com

    I would recommend either of the first two while alldatadiy has most of the factory info online but not as comprehensive as the first two.
