Description & Operation
CAUTION:
When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See 1993 COMPUTER RELEARN PROCEDURES
or 1994 COMPUTER RELEARN PROCEDURES
article in GENERAL INFORMATION before disconnecting battery.
A permanent magnet (PM) motor operates each power window. Each motor raises and lowers the glass when voltage is supplied to it. The direction the motor turns depends on polarity of the supply voltage. The switches control the supply voltage polarity.
The master door lock/power window switch assembly controls both motors. The right window switch controls only the right window motor. Each motor is protected by a built-in circuit breaker. If a window switch is held too long with the window obstructed or after the window is fully up or down, the circuit breaker opens the circuit. The circuit breaker resets automatically as it cools.
