GMC Envoy

My fuel level is not working for my GMC Envoy, so I am doing the trip miles, so I am try to find out how many miles does it take, so I can refuel again?

Probably the stepper motors that control the needles. Common failure and can be ordered on eBay and replaced. We have a how to with pics for the procedure on our enthusiasts forum.

1. Close all the vehicle doors.

2. Insert the ignition key into the ignition lock cylinder.

3. Press and hold the door unlock switch.

4. While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.

5. Release the door unlock switch. The doors will lock and unlock to confirm the program mode.

6. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.

7. Repeat the previous step to program up to 4 transmitters.

8. Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter programming mode.

9. Operate the transmitter functions in order to verify correct system operation. b0i13r

Check your plug gap and that you didn't crack a plug.

The rear wheel bearings in a 2003 Buick Rendezvous are integrated with the hub, therefore they are only available/replaceable as an entire hub assembly. The rear hub assembly costs around $200/each, depending on the specifics of the vehicle (2WD or 4WD).

check you antifreze level if it is low you wont have eat or if you get lots of fog your heater core is bad

the air condition drain line is plugged. our 2003 Envoy has suffered from this for the past 3 years. every couple of weeks i blow air into the drian line (located under the hood) and make sure i see the condensation puddle when parking (air conditioning has to be run before parking)

If you have the code you can change the sensor yourself. The sensor is located on the exhaust manifold. It sometimes is related to something else. For complete info and troubleshooting visit our enthusiasts forum at www.trailvoy.com

Hate to be the bearer of bad news, but My 99 Suburban has had problems with the gas gauge bouncing unexplainably between E and F, and doesn't read correctly. Turns out the Fuel Pump and sending unit attached to it needs to be replaced (just died in my driveway today). It is a time-consuming job, as the fuel pump assembly is located inside the gas tank.

I KNOW IT FITS A GM VECHILE. UPDATE FURTHER WHEN I FIND MORE INFO

There is no harness persay. It appears that GM didn't put a plug in these vehicles so there is no plug-n-play harnesses. The wires are up in the dash and have to be spliced to a brake controller. A friend found this and sent it along. It shows the wire location and basic installation process.

Please be more definitive and let our technical people give you a hand with this at our forum. Is it the speedometer you are having problems with or a wheel speed sensor? Do you have a specific trouble code you can tell us?

Not meant to be adjusted, so not easily adjusted.

It is true that the ride height is not meant to be adjusted, but that doesn't mean that it CAN'T be done.

Above the rear axle, attached to the body of the car is a switch that looks like a small shock absorber. The end attached to the body can be adjusted by moving the mounting point. I would not recommend doing this. Small adjustments to this bracket or the switch could cause a failure of the air ride suspension, and could cause serious injury to people in the car if it failed while the vehicle is in operation.

It is located right on the windshield washer reservoir. It looks like a short black cylinder.

There are two oxygen sensors. One located on the exhaust manifold and one located after the catalytic converter.

when you turn on your a/c it increases the electrical usage from the alternator, have your alternator checked to see if it is charging properly

The cooling fan speed sensor itself is not the culprit. The visco electric fan clutch goes into a lock-up state and the sensor picks up the overspeed condition.

Essentially the fluid silicone material inside goes hard and breaks up and then small pieces get stuck in the valve mechanisms. This causes the clutch to loose it's ability to release.

There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.

The 2004 GMC Envoy air conditioner vacuum hose diagram can be obtained from most Chevrolet dealerships. The diagram can also be found at most auto-parts stores.
