Just began like a month ago, have almost 90,000 on it. Went to a auto shop and had a computer reading done and says nothing wrong?? Sometimes the truck dies cause the idle drops too low. this only happens when im parking going slow. auto shop guy sugested it was the idle control part but he couldn't find the part for the vehicle told me i'd have to go to chevy dealer. Just seein if yall have any clues of what it might be before i go hand my paychecks over to a Chevy Dealer to fix this???

2002 Chevy Silverado - when it's cold, the truck starts but while idling, dogs out then suddenly revs up high

While cold, this revs up then sputters and practically dies. It takes a great while to quit doing this. Could it be a fuel filter or related to the cold otherwise?

Tailgate problems with 2000 Chevrolet Silverado

rudydoo — Sat, 29 Mar 2008 16:35:50 GMT

Would you please advise me how to figure out what has broken or came loose on my tailgate latch? It has been working just fine for years, and yesterday I couldn't lower it. Also, how do I lower it with a broken lock?

My 2007 Chevy Silverado 1500HD kills the battery if it sits unused for 3-4 days. This has been an ongoing issue since day one.

I have had a problem with the battery dying if the truck is not used for more than 3-4 days, I have had the dealer do extensive checks...nothing...

GM has intervened. Nothing. I want to upgrade to a bigger battery, but the space where the battery is won't allow it...we have changed the battery 2 or 3 times now, and the problem persists. Anyone having this issue, and if so, how did you fix it. The truck has almost all available options, so it is power hungry, but it still should not be dying like this when it is not used

I have a 2003 Chevy 1500 HD with 70,000 miles. I need some advice on how to correct a check engine light warning light.

Are the Chevrolet Hybrid pickups available yet, and if so, where? What kinds of reviews do they receive?

We have seen a Silverado and a Sierra hybrid pickup on the Chevrolet website, but we don't know if they are available yet.

Cooling and fuel problems on a 2003 Chevy 1500HD 4x4.

5frankie3 — Wed, 18 Feb 2009 21:47:01 GMT

I have a 2003 Chevy 1500HD 4x4 with Quadrasteer, the vehicle has 98,000 miles. I am looking at extended warranty for 24,000 or 36,000 miles. Wonder if the 6.0 V8 has an inherent problem with either the cooling or fuel systems? This is only covered in the 24,000 plan. I’ve had problems with a 1996 Chevy 1ton 4x4 that I previous owned and wonder if these problems are still present in the 6.0 engine.
Thanks

My Chevy 1500HD is giving me a low oil pressure warning.

m1texas — Mon, 30 Mar 2009 20:28:30 GMT

My Chevy 1500HD is giving me a warning and sound to alert me to the low oil presure. However, it runs will and i tried changing out the o rings and oil pump but it still give me a waring sound of oil presure low.

Can you beef up a 2002 Chevy Silverado 1500HD to tow like a 2500? Thanks.

mattattack2 — Fri, 01 May 2009 17:39:49 GMT

What is the difference between a 2002 1500 HD and the 2002 2500 as far as towing capacity? Can the 1500HD be made to tow like the 2500? I am buying a trailer and do not really want to purchase a larger truck if I can help it. I love my 2002 C/C S/B 1500 HD and the 2500.

[edit] I need additional towing capacity to 12000 lbs

I do want to keep the 1500hd if I can but can not pull the weight of the new 5th wheel I want. Can I do something to the existing truck to make this possible?

2004 Chevrolet Silverado trailer wiring.

seter — Wed, 20 May 2009 12:40:09 GMT

Factory trailer wiring plug. The only power coming out of the plug is taillights. Is there a fuse for the rest?

On the factory trailer plug all I have is the park/tailghts. All the fuses appear to be good. is there a relay or something I'm missing? or does the tow switch on the shift lever have to be on to activate the trailer package?

2001 Chevy 1500HD transfer case not engaging.

jigzzy — Sun, 24 May 2009 12:45:18 GMT

2001 Chevy 1500HD with 4 position push button 4WD on dash, the usual 3 and a auto 4WD button, model 246 transfer case and L480E transmission. previous owner said that while he was "on the throttle" he heard a "clunk" when it went to engage to 4WD. everything outside the transfer case seems to be doing what its supposed to (font end engages, transmission engages when in low, etc) something internal in transfer case must be wrong correct? any ideas? don't mind doing work myself to keep cost down if not too complex

Oil weight for Silverado

rreid2 — Fri, 01 Feb 2008 20:16:47 GMT

1. Even though it calls for 5W30 GM dealerships are using 10W30, is it because of the climate. We live in west texas. I have 10W30 in all my vehicles because I heard of a recall on the Castrol GTX 5W30 oil. And I prefer Castrol GTX. I called GM and they know nothing of the recall. And now I'm in the process of changing out all the vehicles to 5W30 again. Since you answered my question.

I'm confused about weights of oil, what is the difference between 5W30 and 10W30?

rreid2 — Fri, 01 Feb 2008 21:14:14 GMT

I had a 99 Silverado with a 6liter and put 10W30 in it according to the temperatures in the owners manual. Wouldn't it be the same on my 2007 8.1liter GMC Sierra? My 6liter had 190,000 miles on it and never burned oil.
