2001 Boxster S power windows inoperative

[pcaengr]

After a drive in my 2001 Boxster S with the windows down, I discovered they would not go back up. I checked fuse D3, and it is fine. Since I had replaced the battery, I tried holding the window switch down, then pressed down again, then up...still nothing. I am lost and hope someone may have a suggestion.

To be absolutely certain, I'd take a 30 amp fuse from elsewhere and try it. I would note that on my 2003 Boxster the window fuse is D1.

 

Try raising the windows with the key fob.

 

Check if the convertible top is working.

Good idea about using the fob to operate the windows. Helps determine if it's a switch issue. You just hold the lock button for several seconds.

Appreciate all those suggestions but I am getting nowhere fast! The key fob will lock and unlock the doors but, no matter how long I hold the button down, the windows will not roll up. I switched all the 30 amp fuses in the 'D' row and no results. Again, visually, they all look fine. Yesterday, I raised the top, then lowered it back down. Today, I tried to put it back up, but it will not operate at all. I noticed that now the dash indicator light for the top is lit up. It has never been on before. Some more background, the windows haven't worked since last summer when they 'magically' quit functioning. When I started working on the car again yesterday, I removed the driver seat and replaced the 15 amp fuse in the M535 alarm computer. After doing that, the fob started working for the first time! It was completely non-functional before. What it appears I have gained is a key fob that now works, the front and rear trunks now work with both the key fob and also the switches by the side of the driver's seat. The 'lock' button on the dash, the 'top up/down' button on the dash, and the 'defroster' button on the dash do nothing now. I am over 300 miles from a Porsche dealer and don't have any faith in local shops with the car. Hoping I may somehow drive the gremlins out and, with the great knowledge base in Renntech, be able to figure something out! Thanks so much for your suggestions. Any more?

Have you opened the keyfob and carefully inspected the buttons?

They do wear out. If that is the case it is time to replace your 17-year-old key fob.

The windows are supposed to drop a little upon actuating the door handles to aid in being able to open the doors without the windows catching on the convertible top. Does each window drop when opening each door?

This may or may not help, but the electrical component of the ignition switch can throw up all sorts of odd behaviour. As it's a cheap and easy fix, changing it may prove worthwhile.

 

If you have an Audi dealer nearby, their part is interchangeable, and less expensive. 

 

If you can't find a write-up on this here on RennTech, there's a detailed one at pedrosgarage.com
