Frequently Asked Questions
Why does the window work from the driver switch but not the passenger switch?
This indicates the motor and regulator are fine, but the passenger-side switch is faulty. If it works from neither switch, the motor, regulator, or wiring is likely the problem.
Could the window lock button be the problem?
Yes. The window lock button on the driver door panel disables all passenger window switches. If pressed accidentally, the passenger window switches will not respond.
Can a window stuck open be a security issue?
Yes. A window stuck in the open position exposes the interior to weather and theft. If you cannot close the window, cover it with a temporary plastic barrier until repaired.
