Can't get my front and 1 rear 12v outlets how do i get my 12v cigaret outlets working again on my 2004 GMC envoy my 2004 GMC Envoy. Can't find which fuses they are on neither of my fuse boxes.

Answers 2&3 were right...under the left rear seat is a fuse box, pull the nylon webbing in the center of the fold between seat and seat back to release the latch...fuses 46 or 15 should be the ones you're looking for...

Check the wiring harness on the back of the radio to see if it's loose. If you have a Bose system, the amplifier may be going bad.

In the rear fuse panel (under rear seat), check fuse# 46 (AUX PWR)

Replace the front one. The back one flashes like that to let you know the other bulb is out.

I have this same problem currently...did you find anything out about it?

Check the fuses for the power outlets.They are separate than the cigar outlet.They are located under the back rear seat on the drivers side.It will be fuse number 46 for power outlet 1 and 15 for outlet 2.Hope this helps.Good luck.

door lock actuator solenoid ( inside of door) needs to be replaced

Can't go by the pressure. Ck the large lone coming out of firewall, should be col. Small line at ac condensor in front of radiator should be hot.

Static pressure on high side probably 80psI Running 30 on the low side and 1130. will vary depending on oiutside temp Hope this hekoped

I just purchased a 2002 Envoy and had the same problem. If you raise the drivers's side rear seat, you will see a big black box. Remove this box by pulling the bottom of the box outward and it will come straight up. Next you will see a black cover. This cover has a push tab on each end. Push
the tabs at the same time and lift up on the cover and it can be removed. Inside the cover there is a fuse diagram. The fuse number for my 2002 was #46. This fuse controls the front plugs and #15 controls the back plugs. Locate the the fuse puller on the top left, then count over to spare fuse #3. Between #3 and #4 the fuse is located about 1 1/2 inches below those fuses. You will see a yellow 20 amp pin fuse (BP/ATM-20RP AUTOZONE). remove and check fuse.

Good luck
