Hi guys...it's been a while since I visited this sight last. When I had my 89 Camaro.
My father-in-law has a 1994 Trooper and he can't get the headlights to work properly. The normal/low lights do not go on at all. the high beams work, but only if you hold the blinker handle towards you (which is how to switch from low beams to high beams). Once you release the blinker handle, the lights go off.
He knows it that something is wrong with the wiring, (not getting power to the low beams?), but can't figure out the remedy to this.
can you help?

Hope this helps.

Hey Mike,
This is great! I'll give this to my father-in-law and let you know if he
gets the lights working. This diagram is what he was hoping for..awesome!

Mahalo Nui Loa!::grinyes:

sounds like the combination switch and/or relay? the fact that they work at all shows at least the high beam part of the circuit works past the switch...

Thanks, bc

I'll pass this info on as well.

I appreciate you guys taking the time to help.:smile:
