1997 chevy 1500 headlights will not turn on

SOURCE: CHEVY 1500 TRUCK HEADLIGHTS TURN OFF WHEN YOU TURN ON SWITCH

If you have replaced the switch, and it is still doing it it sounds like you definately have a short somewhere in your wiring. On the other hand if the dimmer is in the turn signal arm ( forward bright back dim ) the problem could also be there in the dimmer switch, such as a short being caused by that dimmer switch being faulty.Auto Zone and Discount Auto Parts both test a lot of your electrical problems for free, and/or may have some knowledge to more accurately pin point the problem. Not sure about Pep Boys or some of the other discount auto part chains.

With electrical problems I always look for a bad ground wire, especially on older vehicles. Look for any wire that goes to an inner fender or the engine, there maybe a faulty relay in the circuit too. good luck, Chuck

by looking at the manual for my 97 Camaro and if you say that the switch is good then that helps narrow it down a lot, because i found a circuit breaker... not a fuse!...located inside the headlamp switch itself. good luck and let me know if you find it... c.b's. are usually resetable please let me know if you fix it because i have the same car and it might go out on me someday..thanks man! also you can see if your getting voltage on the yellow wire when the switch is in the "head" position..if its not there, then its almost a guaranty that its the c.b.
