My passenger window has been acting up lately.. It wouldn't always go down, and did it would there would be a lag from when i pressed the switch and when the window actually started to move. In the past couple days however, it hasn't budged no matter how many times i try to roll it down. When I press the switch (both the one on the driver and passenger door) I hear a click, but nothing happens. I assume my motor has gone out, is there anything else I should check?

 

Ya may need to pull off the interior door panel to actually check the motor. Try applying power to the connector bypassing the switch.

While the panel is removed, also inspect the regulator and anything else that may be out of place or binding the window track. If the motor works when jumpered, then check the multiplex unit.
