Driver's Window Doesn't Drop When Opening Door

[Southtxfarmer74]

Go ahead an change the regulator and motor. I did the window regulator first and still had slack as the motor's drive mechanism had some play in it. After I changed the motor, my passenger side window worked perfectly. I found a new OEM Porsche motor on EBay for a 100 bucks. You might have to hunt a little, but you should be able to find the parts for less than $250. Good luck!

If the regulator isn't broken yet, you can fix it by just taking up the slack in the regulator cable. I added a barrel adjuster for a bicycle brake cable on mine and it has fixed it for several years now. My cost was zero, but I expect they are somewhere between 30 cents and 3 dollars. Too see if there is too much slack in the cable lower the window 1/2 way down and then grab the glass and see if it moves up and down excessively. I posted instructions on this easy repair a few years ago, but since then all of the photo I posted have been deleted off the website I was using.

Thanks for the regulator test, Dave. I'm going to try that out now.

I assume the regulator is fine because the window drops correctly when I unlatch the top. This should isolate the problem to the door. Either way, I'll report back on the regulator slack.

Anyone have part numbers for the micro-controllers?

Here is the original thread. Unforutanely the pics have been deleted. Turns out the cable doesn't stretch, but apparently a small plastic guide breaks causing the slack.

I see there are some pics from some others on this forum in the thread and the link on to how to remove the interior door panel, so this thread should give you an idea of how to fix it.

Almost 100% certain it is the regulator only. Typically, the window won't drop when the door is opened because there is slack in the cable. When you open the top, the slack gets taken up and the windows appear to drop evenly about 2". I'd bete if you measured things really precisely, you'd find the windows don't drop exactly the same amount when the top is unlatched.

As others have suggested, there are two options. One is replace the regulator. The other is to brake cable adjustment.

Good luck.

I did the bicycle cable adjuster thing about 3 years ago. Still works like the day I fixed it.

Thanks guys. I bit the bullet and ordered the window regulator. Not too bad of a price on Amazon (120ish) with free shipping. Funny how the regulator in my A4 cost about half for pretty much the same thing with different dimensions. Porsche premium?

I'll report back when I install.

Hope this solves the radio and miles-light-in-gauge-cluster staying on when turning the car off issue too.
