The engine light is always on. We were told that our gas cap needed to be replaced. We did that, and the light went off for a while, but came back on. Mechanics have hooked it up to the conputer, and still cannot figure out the problem.

The backseat speakers have a sound coming out if them that sounds like an airplane picking up speed to fly. It only happens sometimes. If I smack it, it stops making the noise and the music comes out clear.

The 2 AC vents on the driver side blow heat out, even when the AC is on. So I shut the vents to those 2, and use the passenger side vents to keep myself cool. In the winter, all of the vents work correctly to blow out heat.

My GMC Envoy has been working fine and I drove it earlier today to run some errands and parked it at home. 4hrs later my wife gets in to use it, starts it up fine, tries to go in reverse and the car doesn't move. The engine revs up but wont move forward or reverse. Its almost as if it its in park. One thing I did notice is that when I shifted the gear its was a lot smoother when transitioning from Park to the other shifts than any other time. On the dashboard the vehicle still says Park when I shift the gears and also when I shift it isn't allowing me to push my vehicle, its almost as if it is stuck in park even after shifting. My car has 153000 miles. My car has a manual transmission and the transmission oil is good

At times my car will start and run great. But sometimes it wont start acts like battery is dead, if i keep key turned over it eventually will start at least most of the time. Others i have to sit and wait few minutes then it will turn over.

At times they'll come on for a quick moment and then shut off and I have to use my high beams.

Purchases vehicle used and previous owner snapped the antenna off. Now radio is all static. Can't get the mast off because it's bolted down in such a way that I can't figure out how to remove it.

My 2003 gmc envoy has 220,000 miles on it and hasn't had any major problems runs great and still has original breaks but the Number 5 on the AC doesn't work.

There are 4 round air vents on the dash that blow air on the driver and passenger. I installed a new battery and now they don't work. All the other positions on the switch work but it seams that some actuator inside is not functioning to open the vents. What happened and what needs to be done to repair this function.

The CD will not eject.

doors will lock and unlock going down highway. what is going on?

Turn switch to lower speed abs and brake light come on.can you help

Engine cuts off only if I turn on my a/c. Voltage gauge on dashboard fluctuates. A/C does blow out cold air. When air is not on voltage gauge stays at 14 like always. I can run radio, heat, etc. and everything is fine. Battery is brand new, just a few months old.

If I mess with the vpedal they might release

Replace fuse two times cluster fuse

Can use the manual release button to shift out of park but pressing the brake doesn't release the shifter.

I was at a gas station and my truck died with no prior warning. Had tried to jump it off with no results. Had it towed and new battery put in. $124 batterty. Now It wants to stalll out at light with air on and lunges just before it comes to a cimplete stop. Help!?!

I changed my water pump 4 days ago and my girlfriend drove about 400 miles yesterday now the blower motor won't shut off even when the keys are out of ignition and when idling if A\C is on it acts like it going to die bogs down real bad
