Hihi...
there may be loose connections with the bulb socket. so they turn off and on while driving.

now the loose connection might hav developed and the wire might have came out from the socket so the light dosnt glow now.

try checking and putting back the wire in place

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)

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.

High beam works and low beam dont , checked fuses under hood there good , tried new switch stilll no low beam , is there a relay for low beam cant find one.


Why yes there is. It's #46 under the hood. Switch relay #45 with #46, do you now have lights? Either clean the contacts by pushing it in and out of the fuse box, or buy a new relay. Cleaning the relay worked for me, but I keep a spare just in case. Very common problem with Envoys and Trailblazers.

It sounds like you have a faulty high beam/low beam selector switch, if your headlamps aren't blown both on the low side. In order to change it, you also need to pull your steering wheel off, and it is also a part of your derictional switch assembly. Be aware if you have an air bag in the wheel, and if you do find out what you need to do first before disconnecting it, as some vehicles equiped with air bags can go off when you unplug or plug them.
