Headlight problems...... electrical
Sunday, August 12, 2007 1:52 PM
I know many of you guys have done headlight swaps from cavys to fires and vice versa........

i swapped out my 95-99 style cavy lights for 95-02 sunfire lights

I have absolutely no power to the headlight bulbs at all.... as in no voltage through the wires

I first thought ok.... switch..... cause there was no power coming out of the switch to the headlight bulbs....... but i plugged the switch in to my other car which is a sunfire... and i have power coming out of the switch....

so recap.... i have power going into the switch into both cars..... but no power coming back out on only one car...... i know its confusing but what the hell could be the problem?

theres power at the fuses and everything

yeah i swaped the harness...... but thats not the problem..... i have no power to the harness at all except for the parking lamps

could the drl relay be the problem? I have them disabled but i see that power still has to run through it.... so where is the relay located?

You smash the front end or something? Why the Sun-alier conversion?

where did you check where you have power to? at the end of the bulb pigtails? or actually at the harness connector coming from the car before it connects to the fire harness?


was gonna wait for you to reply but I'm almost certain this is your problem because I had the same problem. I know in your old cav you used a sunfire harness or whatever, youve told me that before, but i'm betting your problem is the harness. The pin connectors arent in the same location so your plugging pins into empty slots not making connection with anything. When I tried your method on my green car last year, thats the problem i ran into, only parking lights would and horn worked..

Thats what im thinking your problem is. Your better off splicing your connectors in.

nope...... theres no power coming from the main harness at all..... the pink and blue wire that controls the high and low beams

try swapping back to cavalier and if so does it fix your problem? if so either how the relays are, or your connect pin out is different and causing problems, could be other reasons too but if u swap and that fixes your problem it tells u what your cause is, then i would think about just splicing in.. nothing wrong with it if u do it right(solder and heat shrink)

do you think the fact my car is a 97.... and the harness is from a 95..... that would do it?

cause i know 95 was the bastard year for wiring

both the high and low beam wires have power at the same time

i put the correct year harness in

although the only problem i have is the turn signals flash really fast... whats up with that? and the right turn indicator stays on when i turn the lights on

one of your wires are crossed.

i custom wired my entire headlight side marker and even mirror led's with a friend, we've never had a problem.
