Strange goings on with my Boxster's driver's side window

[Michael Larkin]

So I just bought a 2002 Boxster base a couple months ago.  Very happy with the car, but as it's elderly I have a decently long punch list.  It's had an intermittent issue with the driver's side window that has me perplexed.  When I first got it the window would randomly adjust up and down while driving.  I searched online and discovered that most wacky window behavior could be traced to the micro switch or door latch, so I ordered both.  Prior to installing the switch and latch the problem suddenly went away for about a month.  Unfortunately it recently returned and since I don't like the idea of not being able to lock my doors I decided it was finally time to install the new parts.  Needless to say, it did nothing.  I was ready to go ahead and order a convertible top switch when I discovered that pulling on the door handle made it stop most times.  I also discovered that both door lights were missing, so the previous owner was hip to the issue and neglected to tell me about it.  Oh, well.  I'm guessing that I'm gonna be on a bad wiring hunt this weekend.  Any ideas of where to start?  Anyone else dealt with this phenomena?

Have you tried re-training the window?

Here is what you do - press and hold the window down - once it is all the way down continue to hold for 10 seconds,

Next do the same for window up - hold until up then hold another 10 seconds.

 

Let us know if that fixes it.

Tried it several times today but no luck.  I got it to close the window completely twice but had to return both times to shut off the alarm as the window had auto-dropped again while I was gone.  Tonight when I got home from work I tried one more time as when I closed the door I got a rapid fire auto-drop and back up symphony.  Luckily it wasn't raining on the way home so I just cracked the window a bit to prevent it.  On the way to work this morning I drove with one hand pulling the handle most of the way due to it raining.

Chances are you are going to need to get into the inner door by removing the panel. Besides the microswitches look for wear on the the latch mechanism (for remote locking) as those wear out also. Check the windows regulator (cable) if it is worn replace it.
