My 07CS has an issue with only the passenger side window. Using either the drivers side or passenger side window control switch, if i bring the window down part way, and then click it up to auto-up the window, it brings the window down. and subsequent auto-up-clicks do not bring the window up, I have to manually hold it up to bring the window back up.
I was looking for a thread with this issue but wasn't successful. If it is happening on both the drivers control and the passenger control switch, I have to think its not the switch, its whatever the component is that those two switches lead to, or some point after that in the control. can anyone tell me what that is? Or if there is something I'm missing? The motor seems fine, but im not too familiar with these subsystems.
Any guidance would be great, thanks!
hey there have you tried resetting the window positions?
IIRC move the window to top position, release then hold it in up position for 30 sec.
this should tell the car when the window is in its top position.
I have not tried that, but im not sure why that would fix that pushing either passenger window control switch up brings the window down...
I would not exclude the switches as an issue. The window controls are relatively complicated and take time to troubleshoot. I would probably start with checking the switches open and close state with multi-tester and take it from there. If you decide to do that make sure you disconnect them from the car first. These are digital signals fed into controllers in each of the doors and then referred to the
can bus
in the car. I am attaching the wiring diagram for your reference. If you are uncomfortable dealing with it you may be better taking it somewhere for service. There is a risk of blowing up a gate on the controller and that is going to be expensive. From my experience that is usually a switch issue, although controllers go bad too. Of course as mentioned try the reset first. Good luck!
I have a 2009 and I get this issue sometimes as well
Have you tried anything to fix it? It seems to be a consistent issue with my passenger window, but i dont want to play with it too much for fear of making it worse.
I tried the reset and it did not work. I can't really make out that schematic, does anyone have a higher res image?
This was a common problem reported years back. Search "Window Ghosts." My 987 does this from time to time, my dealer said if nothing is obstructing the glass and the mechanism is ok (it is) it is a software issue reported to Germany. It only happens on the the passenger side when activated on the drivers side with me.
Mine doesn't do it from time to time, it does it every time. Driver's side window has no issue, but both the drivers side switch and the passenger side switch that control the passenger window will create the issue, which makes me thing its either both switches (which I doubt) or the controller that those switches send a signal to. The motor does seem fine though. If it is a software issue, is there no way to get it updated?
