Need replacement for 2003 Envoy On Star antenna

The tail light fuse is under the rear seat on the drivers side.

The sensor is located behind the crank pulley mounted to the timing chain cover.

Hi John,here's a link on removing your power antenna.

My wife drives a 2003 GMC Envoy and has been complaining about this same creaking noise upon breaking or going over speed humps. I researched this topic on the internet high and low and tried everything I read to no avail. I was about to give up and then realized it could be the motor mounts since when you break or go over bumps the engine does have some movement. Sprayed the most interesting looking motor mounts I've ever seen with silicone spray and the noise was gone! My wife has been complaining for years about this noise and now looking back what a simple solution!. By the way my motor mounts where not worn out, the rubber portion of the mount just needed a little lube.

The parking brake on your envoy is like a small set of drum brakes mounted inside the "hat" of your rear rotors. To adjust it, remove the rear wheels and remove the rubber cap on the rotor. If you don't have a rubber cap look at the brake backing plate and look for an access plug. Rotate the rotor and look inside towards the top or bottom for a star wheel. Rotate the star wheel like you would if you were adjusting drum brakes. You want a very small amount of drag on the rotor while rotating it. If you get too much drag, rotate the star wheel the opposite direction.

here's 1996, all I have. Please rate.

no, GM producst are fairly eazy.
there is a trim piece that goes around the radio, held on by push tabs... just dont be afraid to tug at the panel. it will pop off..
then 2-3 bolts mounting the radio.
radio will slide out.
if the antenna is in the window, look for a thin filament where it has to jumper across from the body to the glass.. usually up high, and you'll need to remove the pillar trim.
Have you had any elecrical item replaced recently... ie alternator, battery, blower fan etc?
This will sometimes cause the ground path back to the battery to shift, or has higher magnetic interference than the oem unit.
Hope this points you in the right direction.
I charge $40/hr for troubleshooting which is the national average.
Your local stereo shop should be able to sniff out the problem for you n a reasonable amount of time.

If the antenna isnt there... that may be the problem!! LOL

Have you tried an aftermarket antenna directly to the radio to see if it works properly?

Fixed MAST antennas usually designate a standard 31" antennas protruding from the wheel well on either the passenger or Driver side.... not the bumper.

A solution to the fixed mast/car wash problem is to go with an interior glass mount or hidden antenna. This keeps your wiring out of the outside corrosive environment as well.
