How your Headlight Motors Work., A description with pictures. Options

NOTE: DUE TO MY NOT LOOKING AT THE WIRING DIAGRAM BEFORE POSTING THIS, I HAVE EDITED IT TO REFLECT REALITY!! (IMG:style_emoticons/default/headbang.gif)

I noticed that there is a lot of questions out there relating to how the headlight motors work. So I put this together to see if I can clear it up.

The headlight motor circuit functions like a 3 way light switch in your house. You all have seen them. The one you can turn on at the bottom of the stairs and turn off at the top. Well, when you turn on the headlights in a 914, you turn on the headlight motor. It's rotation turns off the headlight motor when the lights are up, using a set of wiper contacts in the motor.

In the first diagram below, I outline the headlight circuit with the lights in the down position.

There is one fuse for each low beam element--two total. (Plus two more for the two high beams.) Check those.

I'd suspect the high/low beam relay, sitting up on top of the fuse panel. I believe that is the last place that both of the low beams share a common signal.

Oh, if your lights are "stuck" on high beam, then I would also suspect the high/low switch in the turn signal switch assembly.
