STOP USING IT NOW

You need to educate yourself--study OBD 2
Vehicle Systems

We have had check lights for 35 years,no reason
to not know about them or what to do

You do not use any vehicle with a check light or
any dash lights on,they are telling you the vehicle
has system faults, that need to be diagnosed & find
a problem to repair

It shakes,it smells-- but you keep using it,will get
very expensive, if you don't change your ways, when
it comes to motor vehicles

Get it to a dealer or the best local shop you can find

The BEST Shop-- not some highway chain store-- where
you sit for 5 hours & they do little

SOURCE: check engine light on - 2003 gmc envoy XL

That code represents a lower than expected reading for temperature (coolant). First thing to do is check your coolant level, as if it is low, then the sensor can not read correctly. Second, you may have a thermostat that is stuck open, allowing the coolant to cool off too much. The sensor should be mounted on top of the engine, near the thermostat housing.

My friend had the same type of symptoms, there is a spider wed style od hoses under the intake that delivers fuel to all the cylinders that he found to have hairline cracks in it. Found out this is a know problem especially in the 4.3L Vortex

SOURCE: 2006 GMC Envoy XL gas gauge reads empty

The sulfur content in the fuel is contaminating the contacts of the sending unit.

Some people have had good luck with some fuel system cleaners solving this problem. The cheap stuff doesn't seem to do the job.

Not that GM isn't completely exonerated from fault but the gas stations don't do a very good job of watching what the stations sell.

This is a safety feature that the vehicle brings. You need to reset the E.C.U on dealership or it will keep doing it to you. It was probably caused by one single time that you did not closed the fuel cap correctly. Good luck

When I switch my 2005 envoy xl into all whell drive and then drive, when I get out it smells like burnt rubber. It does not smell like that when in 2wd. What could it be?


You can't use 4 wheel on dry or even wet pavement. It must be snow dirt gravel or mud. Pavement will just burn up your tires because the front Axel pulls faster than the rear. When you have good grip there is a friction fight between front and rear tires.

Blower motor not working 2005 GMC sierra resister ground pin burnt


small_car4.png Wiring problem of the 2005 GMC Sierra 1500 6 Failure Date: 07/18/2009

The connector that plugs into the blower motor under the glove box became too hot and melted the plastic resulting in the a/c and heat not to work (this includes the windshield defroster). I've been looking up problems and solutions and found that this is a recurring problem with GMC and chevy trucks yet there has not been any recall, in fact the dealerships have an extremely overpriced kit to fix their faulty wiring. About 66,000 mi.

My 2004 Envoy does not seem to shift right on the highway


With the limited information you provided, it would be a good idea to bring your Envoy to a transmission shop for analysis. Most general repair shops and even many dealers do not do this work because it is so specialized. Bringing it directly to a transmission shop yourself will save the "mark up" charged by general repair shops.

You can expect problems with the transmission if you do not have it serviced regularly. Problems can be intensified if you pull a trailer, drive in hot, dusty areas, or do a lot of stop and go driving and do not perform the scheduled maintenance.

Sometimes, low fluid level can be a source of the problem and other times a change of fluid can solve the problem - but not as often as one would hope. Check the fluid level on the dipstick. Add enough fluid to bring it to the correct level. The fluid should be pinkish/red in color, but will likely be darker if it has been in for a long time. Regardless of color, the fluid should not smell burnt. An improperly shifting / slipping transmission coupled with burnt smelling fluid is an indicator of a potential expensive transmission rebuild on the horizon.

Good luck!
