Rear Windows

The rear window switches are tied in a series circuit to the master window switch. At rest, each switch contact is tied to ground through the master window switch. When the master window switch operates a rear window, battery voltage is applied to one side of the associated rear window motor. The motor drives the window in the corresponding direction.

When you operate a rear window switch, battery voltage is applied to the rear power window motor through CKT 1307. The motor drives the window in the corresponding direction.

Each motor is protected by a built-in electronic circuit breaker PTC. The PTC resistance increases under the following conditions:
^ If you hold a window switch too long with the window obstructed
^ After the window is fully up or down
The resistance returns to normal after the voltage is removed from the motor terminals.
