Description & Operation

Power window system uses a permanent magnet motor to operate each window. Motor operation is controlled by a master window switch assembly alone or in combination with individual window switches. Window is raised or lowered depending on polarity of current applied to window motor.

Some models use a control module to access an express mode of operation. When left front window switch pushed past first detent, module activates relay to apply full battery voltage to window motor. This provides current to quickly and fully open window.

When ignition switch is in RUN position, power for window system is supplied to master window switch assembly through fuse block circuit breaker. When any master window switch is operated, power is applied through single window switch to motor, driving window motor in either direction to either raise or lower window. Each motor is protected by an internal circuit breaker which will reset after switch is released (voltage removed).
