Hi Ghost, Have a look at the head lamp relay. I believe you'll find the problem there. Regards John

SOURCE: INOP low beam and high beams

The problem is the headlight switch itself - it's one of the most common failures on these cars. The part, brand-new, is about $158 from ECSTuning.com. Replacing it involves removing the airbag and steering wheel - not difficult but a little nerve-wracking due to the power of the airbag.

If this is something you want to tackle on your own, reply back here and I can give you a step-by-step on doing the work yourself. Or you can go to a shop/dealer and just have them do it. They'll probably charge you at least two hours' labor, even though it's a 40 minute job. Let me know what you would like to do.

SOURCE: Left rear brake light stopped working but bulb and fuses are OK.

take the bulb back out have someone sit in car apply brake get your self a circuit tester and check to see if this circuit is carrying efficient 12 volt current! some times in cold weather these bulbs get hot with long period of breaking and when released condensate and rust begins and you get what you have perhaps bad socket! this would be a ideal location to begin and probably end,

SOURCE: No Low Beam headlights

If both your low beams are not working your headlights went out and need to be replaced.

SOURCE: low-beams don't work

Nope - it's the combination switch (the lever-switch on the column) that turns the lights on and off. They're notorious for failure. A new one for a slightly newer car (like my 99 A4) runs $158 at ECS Tuning. Yours will be priced in that neighborhood as well. Removal of the airbag and steering wheel is required for changing it out. You can see a procedure at www.audiworld.com - click on Resources, then Tech, and choose either interior or electrical tech articles - it's in one of those areas. It's not difficult but it can be unnerving if you're working with an airbag.

Did you check the fuses with a test light? A fuse can look OK, but unless you test continuity or use a test light, you could be mislead.

Tail lights inoperatrive

Could be one of three things;
1. Check the fuses in the fuse box.
2. If all fuses are OK, check the headlight switch.
3. If this car has 'delay turn off lights' feature, the lighting control module should be checked.

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.

I have a 1996 Jeep Cherokee. Headlight Problem: Year ago? Switched on high beams, complete darkness (low beams don't work at the same time I've come to find out). Solution: Don't turn on...

ok, first ,, check all the bulbs again, and *** make sure that your hands never touch the actual bulb, these lights will turn the oils from your hands into cooking grease when it comes to these bulbs and cause them to blow out much to early on in their life span, , next,, Pull the light switch ( high beam switch towards you for a quick flash of the head light high beams,, if this doesn't make the high beams come on, your problem is going to be in the switch itself ( what your calling the high beam/turn signal lever) before going to that extreme though,, if you have a junk yard near you, go pull one of the relays off a junked vehicle, and stab it into your system one at a time, it could be something as simple as a relay heating up and disconnecting prematurely due to heat ,, if you don't have a junk yard that you can grab a relay,, here is a link that shows how to check them, But its time consuming http://www.youtube.com/watch?v=C8t25GjZ6i4&NR=1
