Please help headlights will not come on but my parking lights will work, but the headlights will not come on on my truck, please send diagram or do we need to troubleshoot a module and if so where is it located. Yes when you pull the dimmer switch back the head lights will come on, and yes the fuses have been checked and are okay,
Then the headlights go out I've replaced the headlight switch, ignition switch, relay. Still can't find the solution.

Do you
have the same problem?
