Driver's side window problem

[slateblue911]

As a new member I have greatly enjoyed these forums. Thanks to those that have responded to my first problem with my water pump.

My '99 Boxster's driver side window just developed some sort of control problem with the automatic up/down feature. Normally, when you open the door the window drops down to clear the top. Mine works fine when you open the door from the inside handle. Once the door is closed the window closes fine. It's when I open it from the outside handle that it has the problem. When I pull the handle the window drops to clear the roof but when I release the handle it goes back up thus hitting the roof when I close the door. Is this a possible sensor problem or could this be a programming issue?

Sounds like the microswitch inside the door handle has failed. Too many plastic parts

Slate:

There are three microswitches inside the door that act on the window to make it drop down that 1/2 inch and then go back up after the door is closed.

Since the problem only happens with the outside door handle, then you at least have definitely eliminated the actual window regulator assembly. Again since it's only with the outside door handle, then it's probably the microswitch that is located directly behind the forward edge of the semi-circular part that is attached to the back of the door handle. The other, less likley possibility is the microswitch that is inside the door lock assembly.

In either case, you are going to have to open up the door panel to have a look.

Here is a link that will show you how to open the door panel: http://www.ecoutez.net/boxster/door-panel-removal/

I had posted a good photo of the microswitch behind the outer door handle about 4 or 5 months ago on this forum. If I find the link, I'll post it here. You might find it by doing a search.
