I have 91 RS Camaro (v8/305) with non-working front headlights. I just replaced the headlight switch and they still don't work. What else could it be? fuse?

 

The headlights arn't fused, but there is a circuit breaker.

First thing I'd do is grab a test light and see if you have power and ground at the headlight socket connectors. Check the tan wire to a chassis ground first. The Tan wire is the low beam power wire. If you have power to the tan wire, then use the testlight from the tan wire to the black wire (which is the actual ground wire). If the testlight doesn't light up then check the ground wires. They's grounded just behind the headlights, the wire should actually be easy to trace if memory serves.

If you have no power at the tan wire, then check out the circuit breaker. What I'd do is pop a 30A fuse in it's place. If it blows then you have a short somewhere.

Also, take a look at the headlight socket connectors and see if they're full of corrosion (same for the headlight prongs). Usually they just get dim when the terminals corrode, but if they get bad enough then they might not work at all.

Try what I said above, let me know if if none of that helps.

 

which fuse do I replace in the circuit breaker. I don't have any documentation about which fuse runs the headlight circuit.

thanks,

Actually, looks like I was wrong about the circuit breaker. The schematic I found for it shows there's a fuseable link. They should be by the battery, behind it I think.

Did you check for power at the sockets?

 

I used a voltmeter at the connectors and there is no power at the connector. further, I didn't see any evidence of corrosion. I will look for that fusable link tomorrow.

thanks

 

I may have located the fusible link near the battery. It appears that there is some kind of black plastic (jacket) link connecting a thinner wire to a thicker wire. On this black link, there is 14 (I guess gauge) stamped on it. The thinner wire has exposed wiring coming through so I used a voltmeter to check for power. I touched the positive terminal of the voltmeter to this exposed wiring and placed the negative terminal of the voltmeter on the negative terminal of the battery. I measured 13.85 volts this way.
