Found the front passenger window on my 2006 DTS wide open this morning. Apparently opened by itself during the night. Definitely started out closed last night. The rear passenger window did the same exact thing a couple of weeks ago.
I had been having an intermittent issue with the driver's side window express "up" not working that seemed corrected yesterday by doing the "hold the window switch in the up position for 30 sec" fix I saw on this forum. I don't know if it was just a coincidence that I reset the driver's window and the front passenger's window got funky.
Also, the driver's side courtesy light in the door will also intermittently stay on after starting the car (need to turn the car off, wait for the dome/courtesy lights to go off and turn car back on to reset).
Is there single module that controls all of these "features" or are there multiple modules involved? Is there a way to reset it (or them) to try and address all of my issues before module replacement?
