Is there another fuse box on the 2003 GMC Envoy besides the one under the hood? My interior lights have quit working and all the fuses under the hood are okay.

The main fuse that controls the entire fuse box is what I found worked for me on my 2003 GMC Envoy. I accidentally touched my wrench to the left side of the fuse while hooking the negative up on my battery causing all my interior lights, radio, a/c etc. to not work. It's only $4.99 at advanced auto. Took me awhile after checking every damn fuse in the car and not finding anything. Hope this helps

there are 4 places the fuses could be. 1. under the dash next to steering column. 2. left side of dash under the cover only seen with door open. 3. right side of dash under cover only seen with door open. 4. under hood under a plastic cover probably to the right near battery.

Under hood fuse panel. Lid has the locations of fuses. There are 2 for the ABS system.

Check your owner's manual for a fuse box diagram and check the appropriate fuses. This may also be a high amp fuse that is in the fuse box under the hood. Please rate this answer, thanks.

Hi! I am having the same problem. My brother hooked the jumper cables to the fuse box now all the things that went wrong with your car isn't working in mine! Please help! I have a 2002 GMC envoy. What did you do to your car to make it work again

There are two fuse boxes/block

One fuse block is located under the hood in the engine

compartment on the driver's side of the vehicle.

Remove the primary cover by pressing the two locking

tabs. Remove the secondary cover by snapping off

while lifting. To reinstall the fuse panel cover, reverse
the sequence.

The 2nd fuse box is located under the rear seat cushion

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
