Headlights not working

My newest car(87) has the auto headlights option and I can't get my headlights to work. All of the parking lights and dash lights come on but no headlights. I tried covering the optical sensor with my hand and still nothing. If I pull back on the dimmer switch the high beam will come on as long as I pull back on the switch. I don't have the owners manual but I think I know what I'm doing. Turn on the headlights switch and roll the sensitivity wheels. Any direction on where to start checking things or am I just running it wrong?

Obvious questions: Did you check for a blown fuse? Loose wiring?

Do the lights come on normally, as in with the standard headlight switch?

If so, you’ll need a wiring schematic to track down the problem and trace the wires. I think Brian here has something he can email you.

Good luck.

Found the problem, Thanks. Previous owner changed out the headlight switch and broke the lock tabs off. The connector wiggled back.
