Re: headlight problems

This just happened to mine tonight. I had to leave it parked at a gas station till tomorrow > This may be a silly question but is the dimmer switch you're speaking of the round push button style switch on the floor (kinda behind the e-brake)?

Re: headlight problems

Awesome, thanks. I was told when I bought the truck about a month and a half ago that the high beams didn't work. The headlights have been working fine until tonight tho. Could this switch have been shorted out maybe and is also what's been causing my battery to drain every few days?

Re: headlight problems

did anyone consider looking in the electrical forum on this board? There's a real nice schematic in the FAQ over there.

Lightbulb Re: headlight problems

OK,
take the drivers side light out it has both it and the passenger side hooked to it. Turn the lights on and with your test light see if it has power to it. If not start back tracking until you find the problem. I beat it's in the head light connector. The connection behind the head lights has a ground wire to and it's broke I bet you. My daughter eclipse was the same way.
Should have read all the post, glad you got it figured out!

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

I bet this post went unnoticed but all I did was cut off the plug and connect the wires back to the switch with some new spades and voila, a month of headaches just went away and I spent no money

Those connections take a beating if you run bright Halogen lights.
I went through about 3 dimmer switches and who know how many wire connectors on my truck in the past couple of years. 55/100 H4 bulbs.
I replaced the dimmer switch and pigtail to the switch with Napa Echlin parts last weekend on mine when I was installing relays for the headlights.
