Should have 10 amp fuse and relay for engine cooling fan and you should have 10 amp ignition fuse and AC RELAY.

SOURCE: The gauges have stopped working ? Fuse under dash seems to be OK ?

Behind the dash is what they call a constant voltage regulator. It controls the guages. It's small and located behind the dash near speedo.

SOURCE: rear window defroster, no driver heated seat

check the ground on the passenger side of the rear window under the trim panel. That is what was wrong with mine.

SOURCE: 2001 subaru outback headlight not working

chapmnfarm: your head lights use a "2" fuse system.
one for the left and one for the right.
The fuse box you are looking for is under the hood on the passenger's side. It is a black box roughly 8 inches long and 4-5 inches wide. When you remove the cover, you will see fuses and relays. What you are looking for is the section in the box which has a cluster of 7 fuses. 3 in one row and 4 in the other. On the outer parameter are two relays. The fuses you are interested in are located in the row of 4 fuses, with the two closest to the "L" shaped part of the box. Both of those should be 15 amp fuses.
The fuse below those should be a 20 amp which is the lighting switch and the one below it is a 15 amp which is for the interior lights and the clock.
Check your harness grounds in the engine compartment near the area you have the problem. There are ground wires which come out of the harness on both sides of the core support. The wires are black in color and have "EYES" crimped onto the ends of the wires. Both of them will probably be located about 4-6 inches below the upper tie bar on each side of the radiator. Odds are that the eyes will be large enough to pass a 6mm bolt through.
I hope what I have given you will resolve your problem. Lem me know,,good luck>>>>>>>>>>>>>>>

I have no low beam headlights. already checked bulbs, fuses, relay and dimmer switch. can you help?

Before you replace the #46 HDM relay (in the fuse block under the hood) try exchanging it with the #45 cooling fan relay and see if your low beam lights work. If they do, the HDM relay (actually solid state module, not a relay) is bad.

2003 GMC Envoy low beam head lights will not come on. The bulbs are not blown, fuse's ok, no power coming to the head light connector. minimal power to the fuse compartment with fuse removed. 9 to 10...

The problem is a Headlight module. Fuse box under the hood has two black modules side by side, the one on your right is the headlight module the one on the left is the fan module. Try swapping them, if the headlights work replace bad module, don't drive vehicle with the bad module in the fan slot. Mine kept going bad because I had a high intensity bulb on one side.

My 2003 gmc envoy headlights randomly go off and don't cone on wat may be causing this issue???

It's your headlight relay. Next time it goes off, switch relay #45 with relay #46, (same model relay, just for the fan). Buy a new relay, but in the mean time, clean the contacts on the relay #45 and the contacts in the fuse box, this should keep you going. I cleaned mine, and it's lasted over a year now, BUT I keep a new relay in the glovebox just in case.

By the way, we're talking about the fuse box in the engine compartment here, not the one under the rear seat.

Heater on my envoy only works on 3-4 setting, could that be the switch.

Thanks for the opportunity to let me help. The blower control switch in your vehicle also uses a blower relay. This relay is generally located on the firewall on the passenger side near the heater fan. You can also look in you vehicle owners manual for the location of the blower relay, it may be also be located in the fuse and relay box under the hood. Generally speaking if the highest setting doesn't work on a GM vehicle it is a high blower Relay. This item is not expensive and can be purchased at most all you local Auto parts stores. If you have a Napa, Orielly's, or AutoZone these stores will also likely help you in the location if you are unable to locate this relay. Here is a general picturepepsiman1967.jpg The installation of this relay is either to remove from the fuse box, or if located near the heater fan housing then you will need to remove the mounting screws, remove the wiring clip, then reverse to install. I hope that this has helped you. D.R. Wilkins

2003 gmc Envoy Low Beam Headlights both quit at the same time. Checked fuses and replaced bulbs. No dice. ????

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,
