It is really common for the connectors to burn up where they plug into the bulb. Double check the connector. if it looks burnt up replace it. Repair kits are available from your local GM dealer. They will know exactly what you need as this is a common problem.

SOURCE: 2006 GMC Envoy low beam

Hello, try to start by checking the headlight relay and headlight fuse. You also may want to check to make sure the bulbs aren't blown out. If those parts check out to be fine and in working order, you may need to replace the turn signal assembly in the steering column. This part controls the hi/low beams. This may sound crazy but, when GM wired their older trucks, they wired the headlights to go from the battery, to the hi/low beam switch, then to the headlight switch (to the left of the steering wheel) then out to the light bulbs. You can kind of test to see if this part is good by making a fist and (with your headlights on) gently hitting the plastic cover for your steering column that is right behind your actual steering wheel. This could cause your headlights to flicker on and off.

Thanks

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.

Low beams dont turn on........... bulbs check ok...................fuses under hood ok.............need help


{: ) I wonder how you checked the fuses and the bulbs. Did you check also the HDM fuse 15amp and the HDM relay both at the underhood fuseblock? Turn on the low beam and check for 12v at the LO beam fuses. If there is voltage at the fuses but the low beam ok bulbs won't light, then there's a wiring issue from your fuseblock going to the bulbs.
But if no voltages on the LO fuses when the low beam is switched on, then the problem could be on the HDM fuse or relay, the headlamp switch, the BCM, or even the fuseblock.

My headlights don't work, but the brights do. What caused this and how can I fix it?


Every headlamp has a bulb inside that has two filaments one for high beam and the other one for low beam, if any of those filament is cut then that beam (High or low) won't work. If your high beam work then your fuse it's ok, so you can visually inspect your headlights bulbs for broken filaments. remove bulb socket and remove the bulb carefully to inspect the filaments. if the filaments are atacched from one terminal to the other then the bulb it's ok, if not replace the bulb.

Low beams don't work; High beams fine. Not the


the high beam switch is at fault
A new one is needed
The directional lever you pull up on to switch to high and low connects to a rod which is going to the high beam switch at the mid section of the steering coluum. It is a headache to change for your on your head replacing this part

My low headlight in my envoy 2002 is down i checked the fuse and still no luck


If this low beam is on one headlight only, I would say that the light is burnt out. Both hi and low beams are on the same bulb.The bulb has 2 filiments, one low and one hi. If you get just one light out , it is most likely a bulb. If you get both sides not working at the same time, it could be something else. You have checked the fuses and deemed them to be o/k. Then you should be checking for headlight bulbs.
