Passenger Window

There are two relays controlling the Up & Down function of the passenger power window. These relays are located in the I.P. harness just above the steering column. The BCM controls the window Up relay coil by controlling power to the relay coil. This circuit has short to ground diagnostics. The BCM controls the ground for the down relay coil. This circuit has open, short to ground or short to voltage diagnostics.
