How do you check the dimmer switch on a 68 vette. Rear lights work fine, well they light and blink not as bright as i would prefer. Front lights do nto come on. The light in the dash reads as if the brights are on all the time.

Unplug it and try another.

Pull the 3 wire connector off the dimmer and check the blue wire for power with the headlights on. If you have power on the blue then jumper the blue to the tan and then the green.

I check the blue wire and power to it is good. i jumped to the other two wires and no front lights. guess that means i should look elsewhere first?

You might have a ground missing to the front lights. Check the headlight connectors for power and then the black wires for ground.

Now you will have to find the green and tan at the engine side of the bulkhead connector and check for power there.
