When I park my car, turn off the engine, exit the vehicle and walk to the passenger side door to retrieve something, the passenger window opens half way down. The car is off. I then have to go back in my car, turn on the accessory power and roll the window back up. It can also happen if I approach the door before starting the car. It happens sporadically, and, of course, cannot be duplicated when I bring it in for service which I have done twice now. Last year I paid to have the window recalibrated, but that did not fix it, so yesterday I brought it back for them to look at it again. Everything in the system "looks fine." They cannot tell me why this is happening. It only happens on the passenger window and happens sporadically.
