Circuit Operation

The power window system is powered by circuit F81 which connects to the accessory tap in the fuse block. The accessory tap receives its feed from the ignition switch on the A38 circuit. Circuit A38 is HOT when the ignition switch is in the RUN position only.

Circuit F81 connects to the master window switch. Circuit Z1 provides ground for the power windows.

A LOCK-OUT feature is provided on the driver's door window switch. When this feature is engaged the other windows in the system will not operate.
