964 power window problem

[porsche gt3]

Hi,

The drivers side power window on my 91 964 has been working intermittantly and now it doesnt work at all. The switches are good. The motor costs a few hundred dollars and i dont want to buy it if something else could be the problem.

Please let me know how to fix this problem.

Thanks

Do a search, The issue has popped up a few times recently.

Cliff notes: Remove the tweeter from the door panel, locate the motor's shaft and give it a whack with a hammer and screwdriver. Check for function.

I just spent last weekend disassembling my driver's side door to determine what the culprit was for a window that would only go a quarter of the way down and would bind. My issue was that the window regulator was all contorted and busted up. Let me tell you, it's a pain the butt to get out even after taking the motor off the assembly. In the end, it only took about 2 hours to replace, but in the sweltering Texas heat, it felt a lot longer.

If you find that the motor is not functioning properly, let me know. I'll gladly sell off the motor for a lot less than a few hundred bucks. The used regulator I bought had a motor on it, and I tested it but ended up reusing my old motor.

Very helpful , especially the hammer trick.

Tonight i tried to open the window and it didnt work, but i heard an electrical drop noise. I then banged it with a hammer and it miraculously worked. What is your take on this? Does the motor need replacement or is there something i can do to fix it?

Jon, I may take you up on your motor offer.

Thanks
