Power Windows: Operation

When ignition switch is in RUN position, power for window system is supplied to master switch assembly through fuse block 30-amp circuit breaker and Delayed Accessory Bus (DAB) relay, located below left side of I/P.

When a switch is operated, power and ground paths are supplied, through the related window switch, to motor. Each motor raises or lowers window. Motors are driven by two wires; one for power and one for ground, depending on switch position. Each motor is protected by an internal circuit breaker which will reset after breaker cools.
