About the same time I got my 79El [two weeks ago] I also got my first computer so as unfamiliar I am with the both I am more unfamiliar with the El camino.
It seems the 79El is having some lighting problems. As you know the high beems are a mystery. When I fistgot the El, the headlights themselves come on then turn off then on and off five or six times then stay on until I turn them off, I thought if that was the only problem then I was doing pretty well .
Then a couple nights ago I wanted to go to get a X-mas tree but the lights wouldn't turn on at all. And now I have no lights, and the front driverside turn signal stays on when the light switch is pulled on.

replace the headlight switch---there is a thermocouple circuit breaker in the switch that causes the on-off-on-off thing---------the dimmer switch is on the column near the brake pedal and is actuated by a lever connected to the multifunction lever.................Dan
