Windows: Description and Operation

The power window system is supplied power from the 30 amp circuit breaker located behind the fuse block. Power for the circuit breaker is supplied on circuit A22 from the ignition switch. This circuit is HOT when the ignition switch is in the RUN position.

Power for the A22 circuit is supplied by the A2 circuit which is HOT at all times and protected by a 40 amp fuse located in the Power Distribution Center (PDC), cavity 2.

Circuit F21 connects from the circuit breaker to both window switches. Circuit F21 is the feed for the switches. Both switches use a bus bar to provide power for the different functions of the switch.

The ground path for the system is through the master window switch on the Z3 circuit.
