Last weekend my son used the Solstice. His girlfriend tried to put the passenger window up. It stopped halfway up but would go down. I checked the forum for troubleshooting ideas and looked through the service manual for the wiring diagram. I pulled the door panel, checking to be sure that the switch was plugged in (it was) and checked for power at the switch (driver's window is working). Sure enough there is power to the switch. I then checked for power out of the switch (not the easiest thing to do when you are working alone) and the meter gave me some strange readings and certainly not the voltage I expected. Since the window motor seemed to be working (at least down) I replaced the switch. All is working now. There appears to be very little on the forum about switch failure. I may take the switch apart to see if I can identify a failure mode. The switch was only $19 so I feel lucky. Have others had this failure?
