SOURCE: battery removal on a 2004 GMC Envoy

The battery is on the right side behind the fuse box. You need a metric set to undo the 3 screws. Theres one that attaches to the body, one to the bar that goes along the top, and theres one on the left side below the vacuum hose and air induction. After you've taken out those three, you should lift the whole thing out(battery and shroud) together. It's hard to take the shroud off before you lift the battery out. After that, you have to pry the shoud off the battery. The two terminals in the back make it hard. Then just go to any auto parts store and they'll give you a new one.

SOURCE: 2002 GMC Envoy Brake Lights Don't Work

It involves a little tricky manouvering under the dash to reach the switch and you need to be very aware of the orientation when fitting. PLEASE BE AWARE that you are messing with the brake pedal and if you fit this part incorrectly you could interfere with the brake pedal travel and cause a dangerous driving situation. Only fit this part once you have fully inspected the part to be removed, and preferably look at a workshop diagram. Some switches are easy some are not. Most take me 10-15 mins.

SOURCE: Need firing order diagram for 2002 gmc envoy

one, five, three, six, two, four

The plastic intake should have this sequence molded into it somewhere, and even the corresponding cylinder numbers in front of their respective holes. Have fun, and thanks for posting on Fixya.com

SOURCE: I need to know how

It would be to hard to tell and show you over the computer.
The best and easiest way for you is to buy a Chilton manual for your car at the autoparts store. The book runs about $20
This book is a do-it-yourself bible. It will show you everything you need to know on how to do maintenance and repair on your vehicle.

I have a 2005 GMC Envoy. Have tail lites but no brake lites. Third lite on top works whet brakes applied


Since the high mounted brake light works you know that the brake light switch is working. Now you need to check the brake light bulbs in the rear tail light assemblies. The brake lights are separate from the tail light (parking or running lights). There are two screws that hold the rear light assemblies in place.

Brake problem


Switch on brake pedal stuck due to dust etc. Many new cars have a safety feature that allow the brake-lights to come on if the brake lever is depressed, even when the ignition is switched off.
If you can get to the switch, a good cleaning with methylated spirits and a small brush should allow it to move freely again. Good luck.
