New member & owner with sunroof problem -help!

[fil911carrera]

Hello, I'm a new Porsche 944 owner and new to the forum. It's a 1989 2.7 manual in guards red.

I have a problem with the sunroof and hope someone would be able to help.

I replaced one of the broken sunroof cogs and discovered yet another problem, the roof only seems to go one way and if I keep the button pressed in the motor keeps retrieving the line that moves the cogs until the lot comes out! When I press the other button the motor does no respond at all! Just wondering if this is a common fault? Does anybody know what can be the cause? Is it a relay? The motor? Or the button?
Please help!

is that with the ignition on, or just in the aux position? - I think what you're describing is correct for sunroof removal - where the rear arms fully retract from the roof. This should happen only when the ignition is in the aux position - try it with the car running instead?

[FONT=arial unicode ms"]Yes, that happens with the key turned once but not with engine running, but still would that justify no movement in the other direction? I'll try it with the engine running and see what happens.

It sounds like you have a problem with the settings of the microswitches in the system ...

Have a look here:

http://www.clarks-garage.com/

... under "Garage Shop Manual" > "Sunroof". It tells you what should go on, and should allow you to diagnose your problem. (If you are capable of changing the cogs then you are more than capable of fiddling the switches if you are patient; it's not a difficult job!)
