Hi guys, i am new on here and i just became the owner of a porsche 924 1980 , i never new much about these cars before but i am falling in love with them, my car was cheap and needs a bit of fixing up but after replacing the timing belt and V belt its driving great

Problem is the pasanger window wont go down and the Hanes manul dosent mention them let alone give pictures or wiring digram can anyone HELP?

i have discoverd that both switches on the drivers door must be working or the pasanger door will not recive power .....put the switch on the pasanger door is broken so i need to replace it ...i put power from the batery direct to the motor and nothing happend so maybe the motor is also broken ....illl keep you posted on how i get on .

thanks in advance Bren

if you put power directly to the motor, and nothing happened... I'd say it's shot Hoss.

This is not an appropriate place for this type of post; this is where instructions on how to fix things are posted, not where questions are asked.

Look at page 272 of your Haynes manual.

You may be able to repair your motor as the mechanism may be stuck, rather than a cooked motor. You'll have to troubleshoot a bit more.

I must have been doing things wrong for a while then if you are not supposed to post questions here. Anyone care to enlighten me as well as bren?

bren, pull out the mechanism (it's fiddly and it will take some manoeuvring but it's do-able). IIRC you remove the glass first and the mechanism will slide out of one of the cut-outs in the door. The old grease in the mechanism will have stiffened and the whole thing will need to be cleaned and re-greased. You might get lucky with the motor. Pull the motor apart and inside there is a little component which contains a bimetallic contact which breaks the circuit to prevent the motor overheating. It is supposed to reset itself but they can fail. Replacements are available (Google the p/n) or if you want to take a chance on it you can bypass the protection. BEWARE if you do that then there is no overtemperature protection for the motor and if anybody strains the motor in future then terrible things could happen. You might get unlucky and the motor windings/brushes have failed in which case you'll need a new one. When you reassemble spend some time aligning the window runners.

Good luck.

That explains it then. I get more and more enlightened every day in this place.

In that case: !tom, you'd better ignore my cheeky comment in your other post. I'll be a bit more careful next time.

FYI the supplement section in the back of the haynes has the wiring schematics for power windows.
Just curious did you also check the ground for the motor?
