A permanent magnet motor operates each of the power side windows. Each motor raises or lowers the glass when voltage is supplied to that motor. The direction the motor turns depends on the polarity of the supply voltage. The side window switches control the supply voltage polarity.
The left front door lock and side window switch controls all the motors. The other window switches controls only the window regulator in that door.
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.
Left Front Window Switch Operation
Place the ignition switch in the RUN position in order to supply battery voltage to the left front door lock and side window switch through the PWR WIND circuit breaker and the CKT 1001 (DK GRN). Press the left front window UP switch in order to supply battery voltage to the left front side window regulator motor through CKT 164 (DK BLU). The window motor is grounded through CKT 165 (BRN) and the window switch DOWN contact.
The regulator motor runs to drive the window to the UP position. Press the DOWN window switch in order to provide battery voltage to the window regulator motor in the opposite direction through CKT 165 (BRN). The window regulator motor is grounded through the CKT 164 and the window switch UP contact. The motor runs in order to drive the window down.
Individual Window Switch Operation
Place the ignition switch in the RUN position in order to supply voltage to the right door lock and side window switch through the PWR WIND circuit breaker and CKT 1001 (DK GRN) to terminal F. Press the UP switch in the right front window switch in order to supply battery voltage to the right front side window regulator motor through CKT 666 (DK BLU). The motor is grounded through the following circuits:
| • | CKT 667 (BRN) -- The down contact in the window switch |
| • | CKT 167 (TAN) -- The down contact in the left front door lock and side window switch |
The motor runs in order to drive the window UP. Press the DOWN window switch in order to supply battery voltage to the window regulator motor in the opposite direction through CKT 667 (BRN).
The motor is grounded through the following circuits:
| • | CKT 666 (DK BLU) -- The up contact in the window switch |
| • | CKT 166 (LT BLU) -- The up contact in the left front door lock and side window switch |
The motor runs in order to drive the window DOWN.
