911 SC sunroof doesn't close properly
 

I bought an 1978 911 SC with a sunroof and I can't make it to work properly.

Problem is - it doesn't close. It's super slow and sounds very pained. So I've put out anything, cleaned and greased anything, tried a different motor. Nothing has changed.

The wires/cables look great, if the motor is not attached to the gear/transmission part it doesn't sound so pained, it spins fast and compared to my other car (where I got the spare motor from as a test motor) - sounds the same. The rubber thing looks good.

Any idea what I could try?

Hey Martin - check out the link below to a tech article from our site; it may give you some good info in helping you troubleshoot.

Have you tried closing it with the manual handle instead of the motor? It may highlight the problem

The black link between motor and trans may look good but has possibly failed.

Thanks Ian for the response - unfortunately, I don't have the handle .. But I might ask a friend, may be he's got one. SmileWavy

Thanks Dmitry, I've read this a few times but couldn't come up with a solution .. Thanks anyway SmileWavy

mhhhh, you might be right .. I'll check that today! Thanks! SmileWavy

No problem. The reason for suggesting this was that I fitted new seals to mine last year and the roof would not close fully afterwards, I assume because of some misalignment of the seals. I closed it using the handle which maybe allowed a little more pressure to be applied than through the motor and it closed fully. It now operates properly. Of course this may not be your problem but it could isolate something. Good luck

Ian

Thank you Ian, yeah, some more pressure might help, right now it's really slow and sounds agonized .. (don't now if that was the right word - google translate helped me) :cool:

Hi Martin..did you remove the sunroof and the cables or just lubed them..if not, i suggest to remove the cables all the way out....or come to Carlsbad -CZ and i will fix it for you;-)

Ivan

Haha, that would be a nice trip indeed SmileWavy I did remove everything, cleaned it, lubed it - so I guess there isn't anything in the way .. We'll see, I keep you updated!

Martin make a video and let me see it;-) what did you use for lubrication??..
yes nice trip Hotels here are very cheap;-) and of course good beer;-)
