Looking for the fuse box

Hi,

Please open your fuse box to check if you notice any fuses that are discolored or (potentially) burnt. if you find one, that fuse might be linked to the dome lights.

To be sure, please call your local advanced auto parts to verify the fuse # is correct and then you can order the fuse through advanced autoparts.

Thank you.

This will show you where the box is and what the fuses control. Make sure you scroll to the bottom of the post.

Rear under seat fuse box.
A fuse for ddm/ driver door module. A circuit breaker for power window. Use a test lite and check voltage at fuse and circuit breaker for power window. For the system, you need voltage and ground.

check the fuse/relay. if it is neither of these check the switch with a multimeter. If you can hear the motor trying to move the glass when you try the switch it may be the regulator needs attention. It may be the motor needs to be replaced.

check fuse and relay along with the switch first then the regulator and motor afterwards. Replacing the small electronics is obviously easier than having to open up the tailgate to check the mechanics of the winedow.

Rear fuse block below left rear seat
underhood fuse block on left side of engine compartment

Fuse #41 in the rear fuse panel located under the rear seat.

Relay in fuse box under hood on driver side wheel well labeled HDM, #46 on 2004 Envoy XUV. Swap with relay #45 labeled "Fan" to test. That was my problem.

Good Luck,
Sam

There are 2 fuse boxes..
first one is under the hood on the driver side (black cover )
second one is under the driver's side second row seat (tilt the seat forward and you'll find it (black cover

First of all did you check the fuses? There should be one for the seats. If they're ok then get a Haynes Repair Manual for your 02 Envoy it'll probably even have illustrations showing you how to do it. Its my best advice, you can get one from just about any auto part store.

Under the rear seat, drivers side.
Black box you will need to remove the cover.
