Headlight Problem on 66 Pontiac Tempest
 

Replaced headlight switch....I have tail lights , but headlights don't come on...what could be the problem....Brake lights and blinkers work fine.....

Try changing the "dimmer switch" Also check the wiring that goes to the dimmer switch,they get corrosion

I had same problem in a mid 60's car,,,the wires had come unplugged from dimmer switch in floor , everything worked except headlights , ,,Paul
