1995 Chevy Monte Carlo Only WorkingTail Ligihts and reverse

Hi, did you check voltage circuit At the headlamp? Tan wire is voltage for low beam, Lite green wire is voltage for high beam. Use a testlite on the voltage circuits. I can help you track the circuit,but, you have to do the actual testing. That circuit comes from the dimmer switch. The feed to the dimmer switch is a yellow wire, comes from the headlamp switch. There is a headlamp circuit breaker in the underhood fuse box, check the breaker, use a testlite on the circuit, see if it is hot?
