I have a 1990 300zx n/a and I need help with the headlights. When I turn on my headlights I have no low beam headlights, taillights or dash lights. Instead my high beams come on and won't go off. I have checked all fuses, the dimmer relay, the headlight control switch and the dimmer switch on the turn signal post. I know this is a known issue, I just don't know the fix. Someone please help.

Not a problem I'm familiar with but try searching on twinturbo.net, a lot more info stored there. Beyond that, get a manual and start tracing the circuit, checking all your connections, power supplies, signals and grounds.

Electrical problems ****ing suck.
