PostSubject: Random Hood light and twilight sentinel issue   Thu Aug 23, 2012 1:34 pm

Weird grouping i know but i noticed when one works the other does as well. Oddly they only worked for a couple of days after i recently replaced crank sensor and harmonic balancer. then poof not working again. I am guessing a ground but with no luck finding an electrical schematic i haven't been able to chase it down was wondering if anyone could point me in the right direction to look or possibly has a wiring diagram.

Ambient light sensor. Change it.

I appreciate it. I didn't realize those could be intermittent =)

Everything on these cars can be intermittent. When mine failed, my headlights would be on during the day and the dash would dim so that I could not read it. It would work right every so often. Changed the sensor, and it's fine.
