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

The idle air control valve will be located at the top of the engine on top of the intake manifold. If you hold the new valve and then look at the manifold you should see where it goes. I'm guessing it'll have 2 screws and 1 electrical connector. The one's that I've replaced were very easy to get to and replace. Not sure on your vehicle. The screws may be phillips or torx type heads. Good luck, if this helps please rate this. Thanks.

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!

should be on the passenger side under the dash. Remove the lower dash panel and look up under the dash. you will see the blower motor and then to the left a little you will see a plug attached to a relay/resistor switch. It is held on by two screws. The Envoy is the Trailblazers sister so you may have the same issue I had. Seems like the ground is not sufficient enough causing the ground wire to get hot melting the plugs together. I had a very hard time getting them apart but did. Purchased a new relay/resistor switch and repaired the wiring myself. GM wants $100.00 bucks for the plug. Hopefully you don't have a G/F or wife like mine that thought kicking the fan speed control switch would make it work. I had to also replace that due to her breaking the switch.
