GMC Envoy

Depends on what it is doing or not doing. Transmitter not working? Lighting strike can erase code in opener and need to be reset. Not shutting can be pressure sensitivity to light, sensors at base of door opening blocked or not working. Should have indicator light on each. A staple cutting into wire leading to sensor or wall switch. Odd openings can be someone close with same frequency. If not opening from far enough away, something can be blocking the antenna from picking up signal. There should be 6-8 inch single strand wire from bottom of opener. This is the antenna. A longer piece can be added to this to increase the reception. Troubleshooting: The source of the remote control range problem you may be having could be in your house. At the circuit box, turn off all circuits except the garage door opener. Test the opener. If the problem is eliminated, turn on each circuit one-by-one until the unit presents the reduced range problem. When you find it you will have a short list of home appliances which cause the problem. From there, unplug everything on that circuit and re-plug one-by-one until you find the culprit. Note: the culprit might be on the same circuit as the opener (then you have to unplug everything on that circuit).

Once you find the culprit, you might be able to use the appliance if you plug it into a different phase (see AC phase in Home Electricity). Or, if the culprit is on the same circuit you might simply need to move it to a different circuit.

The 2002 GMC Envoy typically has two oxygen sensors located on the exhaust system. The upstream oxygen sensor is usually located near the exhaust manifold before the catalytic converter, while the downstream oxygen sensor is typically located after the catalytic converter.

After you set. Hold button until you hear 2 beeps

You may also need to navigate through the on board menu located below the speedometer and above the steering wheel. The control buttons are on the steering wheel. There you will find options on when you want the setting to take place. Option like do you want them activate when you deactivate the alarm or when you put the key in the ignition. Also you may want to activate the easy exit option which will automatically move the seat back when the key is removed.

disconnect battery, drain coolant, remove fan shroud, fan clutch, and water pump pulley. remove water pump, clean mating surface on block. apply RTV sealant to both sides of new gasket, install water pump and torque bolts to proper torque, install pump pulley and torque to proper setting. Remainder of procedure is reverse of removal.

There should be a button on your truck that looks like a truck sliding or swirving. Press the button and traction control off should appear on your dash.

where is the blower motor resistor located on 2002 gmc envoy?

probably no gas, if there is gas then your gauge in the tank is broken or frozen

The question you ask is too involved for a proper answer. You need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library

U disconnect the wire @ the sending unit-the gauge should either go 2 empty or full THEN ground the sending unit wire & the gauge should do the opposite IF the guage does this then U need A SENDING UNIT-NOT A Guage.check with the key on 4 a short period of time.BE VERY CAREFUL IF ITS THE SENDING UNIT

i have a vibration in my gmc envoy when it idles and have been told that can be caused by a vacuum leak. i am currently trying to find out how to find the leak. advanced auto parts will loan you a pressure tester to try to detect the leak. i have not gotten the tester yet. would like to know where to look for it for this sort of leak before i get the tester and i am still in the process of getting that information.

There are 2 Oxygen sensors. One is on the exhaust manifold and the other is after the catalytic converter. There are other conditions that will throw a code for an O2 sensor. It is an uncommon failure and worth about $100 so make sure that is your problem and not something simple like a vacuum leak being detected by the sensor.

The best way that I have found is to take off the hoses, loosen the oil pipes at the bottom and take off the fan and shroud by removing the bolts holding it in place. You need to take off the fan which requires a special tool to loosen it from the water pump.

After that, the process should be simple enough. There are two plastic hooks on both sides of the radiator. You can loosen the hold of these hooks by wedging a regular screwdriver between the rubber flap that holds it in place.

The condenser and radiator should be loose enough to unscrew the bolts connecting the radiator and condenser together. Lift up on the radiator and you replace in reverse.

They are located along the top of the motor cenerline. You must remove the plastic resonator that says Vortec 4200. That will expose the coil packs that have electrical connections to them. Remove the bolts and lift the coil pack to the side to reveal the plug. Remove as you would any plug.

Replace with AC Delco iridium.

The coilpack for the rear cylinder is under the cowl and takes a long reach but a long extension will fit just right for removing the plug. The coilpack in the front has a plastic wire guard mounted over the access bolt. Forget about taking this wire guard off but do take the top off by popping the latches. This will give you enough room to get a socket on the bolt and when you get it loose, just turn the coilpack to your left at about 8 o'clock, and you should be able to pull it out.

In a 2002 GMC Envoy, the factory amplifier is typically located behind the rear passenger side panel. To access it, you may need to remove the trim panel on that side of the vehicle. The amp is usually mounted to the body of the vehicle, near the rear speaker area. Make sure to disconnect the battery before attempting to access or remove the amplifier.

These engines are very fussy about having a clean throttle body. The stalling is quite common when it gets dirty. We have complete instructions on cleaning and other maintenance tips at our enthusiasts forum

Attached are mats for when 3rd row is folded down for space to be used for cargo.

if the unit has 4 wheel air suspension then the frt sensors are located on the lower frt control arm and on the rear control arms in the rear if it only has rear air suspension the sensor is located on the rear axle on the drivers side and is attached on the frame it is a very simple level sensor

There are pages and pages and items that can cause a check engine light. You need to have it checked for codes with a scan tool. After repair light can be shut off with scan tool.

There can be many reasons why the heated seats in a car stopped working. A few reasons are, the fuse could be blow, the wiring could be out, the switch could be broken, or it is not getting enough electricity.

That is known as non sustainable development.
