Pop up Head lights go up and down when turned off
 

My head lights seem fine except when I shut them down. They will continue going up and down repeatedly 5-10 times before they stop. Not the lights but the cups open and close on their own. Any ideas what to look at??
Thanks,

This reminds me of when I accidently installed a four-way flasher relay (which looked identical) in place of the headlight relay in my '82 928. Simply put, I'd test the headlight motor and the headlights relay.

The relay mounted on the headlight lifting motor is suspect.

That or the rotary contacts in the headlight motor assembly. These can be cleaned.

way OT but..
had a workmate that liked to play practical jokes so one day I got him back...

I crawled under his car and connected his headlights to his horn.. signal lights would have been funnier. but didn't want to cut or damage his wiring.

I used a big fat red wire so that I figured when he opened his hood he could figure it out straight away... lol


he came in the next day, no reaction, so I said "oh I guess you dint go out last night".. lol.. he just gave me a quizzical look.


i tkind of backfired, next night he got in after drinking a few beer, started the car turned on the headlights all in one go.. and then couldn't shut his horn off ;-) the beer probably didnt help..

I had figured he'd find it as soon as he turned his lights on, it was a junky old dodge dart.. we laughed about it later.. - kids lol..

agree with the above on the headlight up and down issue.

I thought I's start him on the easier check first. ;)

I replaced the relay on the headlight motor which seemed to help. Then it started flipping again. I cleaned the contacts on the relay wires and so far it’s been good. But the other day, the lights got stuck halfway, which closed when I flipped off the lights. I think after 40 years, the mechanics of this archaic headlight mechanism are just tired. I found the more I use them, the less problems I get.
