It's your relay in the fuse box under the hood #46. There is a re-call for this issue. Just replace it, and keep a spare, it will happen again. There is no permanent fix from the re-call yet as of a few months ago.

My low beam headlights won't turn on in 2004 gmc envoy


It's the headlamp relay #46. If you want to test it, swap it out with the cooling fan relay #45 and see if your headlights work. If they do you know this is the fix. Found the solution online a couple of years ago and it was spot-on. The part was $45 at autozone at the time.

GMC Envoy 2003 SLT only the parking lights and fog lights work. The low beam and high beam don't work. Please help


Well, the problem is that I dont know the reason, you should investigate. There could be issues with lamps (must get new) or electricity problems (must head to auto-service)

Need to turn on headlights of 2004 gmc envoy slt while still in park


See the figure below. Use the headlight selector to turn on the low beams, even when in Park.

2004 envoy xuv low beams went out all other lights work checked fuses and switched relays 45 and 46 and still not working any ideas?


Try to see if the bulbs blew out by replacing the bulbs first. If they still won't light, it could be bad grounds or connections or bad continuity in the wiring to the headlight relays or switch. Good luck on this repair.

2004 envoy xuv low beams dont work switched fuses 45 and 46 still nothing any ideas


Other possibilities are; the bulbs themselves, burnt or corroded bulb sockets, or a bad headlight selector switch.

Checked fuses , relay, dimmer switch in my 2004 GMC envoy, still no low beam headlights. Pleas help:(


If you have checked and discounted the relay, the only things left are the headlight switch and the wiring and to the headlights. Try the switch first. It is not impossible that both bulb's low beam filaments may have fused at the same time, unlikely but not impossibly. (It will not be fuses, unless two fuses blew together).

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,
Sam

2004 Envoy, low beam headlights turn off on their own.


the daytime running light module is no good.,or the relay is overheating and cutting out and comes back on when cool.get some freeze spray from an electronic supplier and spray the suspect component when it stops working.the -60f will make it appear fast..cheers
