Light Motor Problem
#1

While driving home today I turned on my lights. They came up and on.

I then left the underground garage and turned off the lights. The lamps went off as did the instrument gauges, but the lamps did not rotate back down. I tried several times but the housing would not rotate down.



I pulled over, turned off the car. The lamps stayed up, no buzzer. I started the car with the lights off yet still up.

Tried a few times while driving and they finally responded and rotated down. I tried turning the lights on and off several times without the problem coming back.



Anyone ever had this happen to them? I know better than to think that this is not going to happen again...after all its a 968!



Comments/suggestions appreciated.

I could be wrong but that sounds like a failed motor relay. Try tapping it or pulling it apart to clean the contacts.

I've had three of these series of cars and had the same problem, all fixed this way:



If cleaning contacts on relay in fuse box doesn't work, you have to take apart the motor and clean the contacts. On our cars it's TWO motors (of course!)



My 968 was doing the same thing, spent 2 months trying everything, finally broke down and took the motors apart. It's not easy, you have to cut the rubber housing and peel it back. Then you'll see some screws, remove them and when you take the top off you'll see the contacts and the place they ride on. I cleaned all the grease off real good, then sanded the contacts and the tracks they ride on. Cleaned it up, put a LITTLE grease back in some places and put it all back together.



Funny thing was after this they still were a liitle goofy for about a week then voila! Now they go up and down everytime...

the mechanism is prone to corrosion and contamination - when this happens, the resistance to movement is too high, and it won't go down



try shooting a penetrating oil (like Tri-Flow, not like WD-40) in there at all of the moving parts

I had one light do that when it was warm outside. The two parts that pull the light (the motor arm and the receiving end) simply got a bit swelled with the heat such that the arm didn't fit as snugly and, since the linkage was dirty, the resistance was too much. I assume that this is na safety feature to avoid destroying motors. The arm just pulled out of the socket and the light stayed up. You could just push it home and would click into place. I simply lubricated the entire arm assembly (not really simply as the access is limited) and the problem disappeared. try it.
