The headlights on the envoy are the easiest parts of the car to repair. You just pull the two tabs at the top of the headlights, screw out the bulb containers and you are good to go

SOURCE: 2003 GMC Sierra heater Blower wont shut off

My 2003 Sierra's blower came on by itself in the garage while I was sleeping and ran the battery completely down. I had to replace the blower switch located under the glove box next to the blower at the bottom of the right corner of the dash. The switch is in front of the blower and held in by two screws. Disconnect the two wire connections. This is a "dealer only" part and cost me 65.00. Also check the wire harness with seven wires connected to it for melted plastic. It will be marked "ABCDEFG". If it has melted, you'll need to replace it. Pay attention when reinstalling either part, that the wires "ABCDEFG" match the switch in that order.

SOURCE: how do you change brakes on a 2003 gmc envoy

don't need any special tools, standard sockets sets, "C" clams is a must unless your a He-Man and wrench set, plyer or needle nose will do. I assumed being 2003 your rotor never have been turn and i recommend every time you change your bakes is good idea to have your rotor turn. reason is it will make your pad last lot longer, removed any vibration and better even wear on the pad and eliminate any squealing although is not necessary to do so. make sure you get extra break fluid to bleed the brakes. get your self 5 feet long smallest vacum rubber hoses and a glass jar to bleed your brake fluid in. the rubber vacum hose you going to use to fit on to the bleeding nipple and run the other end of line to your the glass jar to save the brake fluid when you bleed the brakes. when removing caliper, check inspect make sure the rubber seals around your piston look good and not crack or deteriorated. before applying new pad make sure you open the bleed valve to reduce the pressure by turning the bleed nipple counter clockwise and leave it open attach that rubber hoses to the nipple because you going to press on the piston back into it housing with the "C" clamp in order for new pad to fit. becareful not to damage the rubber seals around the piston. its going to take lots of effort to push that piston back in so be a bare with it if needs to. once the pad is back in make sure you keep the reservoir full with brake fluid and then bleed the brake. two people is a good idea to do brake. one will do the pumping the brake and holding it down and other will bleed the nipple. I bleed it 2-3 time will do the job. good luck!

The switch on the dash could be defective or look for a module near the heater fan on the fire wall side of the engine dept. Trace the wire attached to the fan motor back to help find the module, check it with your nose to see if it smells burned. You will not mistaken the smell of burned electrical components.

Heater clicking noise in gmc envoy


Do you hear a clicking noise when you turn your truck on? Its probably the actuator. While the defroster was on I removed the fuse locted under the rear driver side seat. I think its 36B. It stopped the clicking noise and my air vents work well now.

I'm stuck out of town and ran the Envoy out of gas, it will not even turn over acts like a dead battery flagged down a driver tryed to jump it. The vehicle still acts dead. Is there a reset button...


I would try cleaning the battery cables.

If that doesn't do it start checking the big fuses onder the hood... they are MAXI-Fuses.

This is assuming you are getting no lights on the dash. IE the the bulb checks you gt when you turn the key.
