Power Windows: Description
Each power window is moved by a single permanent magnet motor. The direction in which motor turns depends on the polarity of the voltage applied. A master power window switch is located on driver's door. Each passenger window switch controls only the window at that passenger's position.
All power window motors have a self-resetting circuit breaker built into them. The circuit breaker allows the motor to be stalled without damage. No travel-limit switches are used.
On Blazer and Jimmy the tailgate window is operated by an instrument panel mounted switch or by an external key switch located in the tailgate door. The window retracts into tailgate door.
A cut-out switch prevents operation of the window by either switch when the tailgate is open. Circuit is protected by a 30-amp circuit breaker, located at fuse block.
