Power Window Operation

CIRCUIT OPERATION
Circuit A25O from fuse 11 in the Power Distribution Center (PDC) powers circuit F81 through the circuit breaker in cavity 2 of the junction block. Circuit F81 supplies power to the Drivers Door Module (DDM) and the Passengers Door Module (PDM). The DDM and PDM operate the power windows. Circuit Z1 provides ground for the power window system.

All four power windows can be controlled by the switches on the Drivers Door Module (DDM). Additionally, the left rear window as well as the right front and right rear windows have separate switches.

The switch pod on the DDM a contains lock out switch. The lock-out feature prevents the windows from being operated by any switch other than the drivers door switch.

Each rear window switch contains an Light Emitting Diode (LED). The DDM prevents illumination of the LEDs when the operator selects the window lock-out feature.
