1991 240sx (non-HUD)

I was wondering if anybody had an idea about this. At night I drove over to a friend's house (with everything working) and left it overnight. Then when I picked it up the next night and turned on the lights, the gauge cluster and A/C control lights didn't come on. I checked all the fuses, swapped headlight control switches, and messed around with the dimmer switch. All the warning lights and turn signal lights still work fine. Any ideas?

wiring?

Didn't change anything on the wiring. The car was left alone overnight.

could be a wire came lose or something like that, check the wires that suply the power and ground for theose lights.

loose wire or burnt bulb

Also, the Lights-on warning bell doesn't not come on when turning the lights on and the keys out. This rules out a burnt bulb. I'm pretty sure it's not a loose wire either as it literally happened over night with the car just sitting...

stranger things have happened maybe some wirs got crossed sometimes shit like that can happen over night i know its strange

did you check relays? it could also be a wire coming from your harness

Just in case somebody is still following this thread, I fixed the problem. The small white box (I guess the TCU) located behind the driver side kickpanel had to be disconnected and reconnected. Don't ask me why -- My career is electronics (Air Force) and "re-seating cables" fixes about 50% of all problems.
