My car thinks drivers side door is open/window problem

[986_Ron]

So I come back from vacation last week and decide to take the 986 for a cruise and notice that the drivers side window is not all the way up. It's opened the 1/4" or so that it normally does when you pull on one of the door handles to open the door. I disconnected the battery for a while, reconnected it, lowered the window all the way down, took it all the way back up and it immediately drops down the 1/4" like it does to clear the top when opening or closing the door. When driving I can't lock the doors and both door lights stay on. Clearly the computer thinks a door is open. I'm guessing it's a micro switch somewhere near the door latch. Or maybe a micro switch on one of the door handles. Has anyone had this problem? Where should I start troubleshooting?

you may want to start here before taking the door panel off

this tests the micro switch in the door mechanism by the latch
search using "window"you'll get tons of thread with door/window discussion

good luck

If not and your Key will. I would guess the door lock mechanism is un-plugged inside the door. I also had red light on the dash and the horn beeped once if I used the remote.

Thanks, that link helps a lot. I'm going to have to replace the regulator on the passenger side. I figure I'll order everything I need at once. My car has over 100k and little repair stuff like this is starting to pop up.

Keith, if I try to lock the door using either the key fob or the dash button it won't lock. Something is telling the locking controller (unless it's bad) that the door isn't closed or one of the door handle micro switches is telling it that the handle is being pulled. I have a feeling I'm going to have to pull off the door cover and do some closer visual inspection...

I just did a little experiment.
while keeping the door tight against the car frame, I pulled the outer door handle and pressed the lock button on the key. it energized the motor in the door and the alarm indicator LED came on.

with the door open, I pressed the lock button on the key, the door motor energized, the car beeped but did not arm the alarm.

does your car beep, the alarm LED flash or the door lock led flash?

from my previous door mechanism activity, if the harness is not connected, no light when the door is opened but the latch works like a normal door
