The rear left vent window on my SUV will not open. The rear right vent window opens, but the left window does not even sound as if there is any power going to it at all. What could be wrong? Is there a way to open them manually? Help! Any and all information will be appreciated!

If they are power windows no way to open manually. Try slamming door then try to open window if it works the motor is bad. If not it will need scanning for codes to see if module is bad.

Hello,

Since the one window still works (I assume) I would think it is the motor that has gone out. Two double check test for power at the motor to confirm. Here are some diagrams and a guide to help you get the problem fixed.

Please let me know if you need anything else to get the problem fixed.

Best, Ken
