Window comes down but goes back up again???


Recommended Posts

Can anyone please help me with my power window's problem?

Here is the Problem:

When I pull on the inside or outside door handle, the driver window will comes down alittle normally, but once i release the handle, it won't stay down alittle for me to close the door. Instead, the window immediately goes back up to the fully closed position.

All the other function of the window works.

I did try replacing part #14 microswitch, but the problem persist. So, did the window regulator went bad, or if there is relay problem?

Doesn't strike me as being a regulator problem. The only reason the window would go back up is if the car thinks the door is closed. This could be a sensor problem, a wiring problem or a computer problem.

Sorry this isn't a lot of help other than I'm pretty sure it's not a regulator problem.

Good luck and please let us know what it turns out to be when you find out.

(text) It sounds like a defective door lock mechanism on the drivers side. Also the early Boxsters had a problem with water getting into the connector on the A-pillar to the body from the door and corroding the wires. I would check the wiring there first before I would condemn a door lock mechanism

tnks.

has anyone a pic of this "A-pillar" ?

and where are these wiring to check? (door/body)

The trick didn't worked :(

At beginning it seems to work (I've lubed all relays) but than suddenly the problems reappeared.

I notice that major problem with window control is when the car is very hot , example when it rest parked on the sun.

Your problem would appear to be the microswitch in the door lock assembly which senses if the door is open or closed. If it is stuck, and the alarm module thinks the door is closed all the time, then the window will go up as soon as you release the handle.

This is the offending item, but it isn't available as a separate part from Porsche. I believe it is a Burgess microswitch, but I can't find a part number for it.
