Re: Problem with my headlights
Well you obviously have power to the dimmer... and grounds to the headlights.
I would recommend getting a basic test light the probing the circuit to see where you do and do not have power:
1. Low beam output of dimmer switch - likely good.
2. Passenger compartment side of firewall bulkhead.
3. Engine side of firewall bulkhead.
4. Headlight socket.
Not too much that can go wrong here. You have verified that all 4 lights are on on high beam?
