1. Driver Power Window Malfunction 2. Front Passenger Window Malfunction

### Circuit/System Description

The front power windows are controlled by the driver window switch, front passenger window switch and the rear fuse block. The driver window switch contains the master power window switch that controls all power window operations. When a power window switch is activated to a desired position, power window switch will send a signal to it’s respective door window motor to move the window to the desired position. The window motors may also receive a comfort closing command from the rear fuse block which will cause all windows to perform the express down function.
