I can loosen them and slide them but I'd like to remove them. I read somewhere that it would improve fuel economy.

When the light first came on the cap was loose, but the light does not go away after tigjtening the fuel cap

The rear gate wiper motor failed and I had it rebuilt. I put the motor back in and when I try to put the window up the computer says "rear wiper obstruction". When I turn on the wiper it says "close rear glass".

When i park my vehicle overnight the rear sags. When i start in am the rear will come back up to height. This does not happen all the time.

I fill up with gas but the fuel light stays in empty mode.It sometimes moves backwards then forward indicating a full tank one minute then empty the next, does this mean that fuel pump need replacing?

Another dught I have is if it is going to start without the flashing, or should I replace it outside the dealer incase it does not start?

I recently purchased a 2005 GMC Envoy SLE, and the lights malfunction, the passenger window will not roll down (already replaced the motor), the doors will not unlock half of the time or when driving they switch from lock/unlock. I was told the truck had been submerged in water and the complete electrical system needs to be replaced.

We have already had the fuel level sensor failure problem fixed and have replaced the gas cap when the check engine light would come on intermittantly. Took the car to the shop for maintencence and they could find nothing wrong that would cause the check engine light to be on, so they reset the light. Subsequently, the light came back on (incidentally right after we hit a pothole) and has been on ever since. Any one else have this experience?

This is the 3 time this has happend

power driver seat will do everything but in cline back. help please

It could be a catalytic converter. However, it could be an O2 sensor or other item. The Envoy seems to idle poorly in park, with the RPMs moving from 300-800. It is like it can't determine where to idle. It seems worse with the air conditioning running in hot weather. I had a cylinder 4 misfire that I fixed by replacing the boot/coil, but didn't get the P0420 until after that was fixed.

I does come back on every once in a while and the air blows cold air. It may work for a couple of days and then go out again. (0nly in the front seat)

It worked but every setting resulting in the air or heat coming out of the defrost vents.

Driving down the road with low beams on, they sometimes go off randomly... I can then either turn on my fog lights so that I have some light or go back to high beams, but still no low beams, then on thier own, they might come back on at some point....

If I could be more specific I could probably fix it my self.

I need to change the unit

how much should it cost to replace oil pan gasket

If you do not have the transfer control module will it cause problems

I have been told the fan clutch on my envoy is bad. I have been quoted repair cost from $300 to $850. The engine has a growl on acceleration. I was told the transmission is OK.

Air compressor for rear air springs fail, causing vehicle to sit very low every time car is turned off.

Air compressor for rear airsprings fail causing rear suspension to sit very low

air compressor for rear air springs fail, causing rear suspensions to sit very low

Mechanics have checked the starter, battery, all the fuses and the alternator. Can't figure out the problem

automatic hydraulic system constantly depresses and back

had radiator busted and transmission mixed with coolant, took it to AAMCO and $3100 later a foul smell came from engine compartment. Battery exploded, took it back to AAMCO, replaced battery for $140. Drove it out of AAMCO, now the radio only has high frequency (treble) and no midrange or low (base). Also the rear speakers are completely silent. I am looking for bulldozer to run this piece of crap over but I have no money to replace it so I am stuck. I held out for 25 years buying American while most of the people I know are happily enjoying their Japanese vehicles. I am thinking of jumping ships and it is a shame.
Any idea what caused the radio malfunction?

raised car up pushed gas and oil came spuing out....i see two hoses is it coming from them or leaking out and makes it appear that way....sorry to confused

Every once in a while and it seems it's when I push the "Driver 1 or 2" button my dash lights go crazy. All of the lights on my dash start circulating...ABS light comes on, then to seat belt light, then to driver info, on to mileage, battery light comes on, etc and it starts all over. I'm afraid that my car is going to stall or something. Any ideas what is causing this. I haven't had any diagnostic codes come up or check engine lights either except for the loose gas cap light. My car is in relatively good condition but has 120,000 miles.

It's like coming from the front defrost vent area.

interior lights stay on after all doors are shut, keyless entry doesn't work, rear wiper not working. All of these issues happened after I put grocery's in the back.

The boot has cut loose @ the clamp.It is coming out right there.Did a hose bust or what is causing the leak or where is it originating from?
