The power window system consists of the following components:

Battery voltage is applied from the WINDOWS 30 amp circuit breaker through the battery positive voltage circuit to the retained accessory power relay (RAP). The RAP relay supplies voltage through the RAP relay switch supply voltage circuit to the LH window switch under the following conditions:

When an UP switch on the LH window switch is operated, the battery voltage is applied to the power window motor. The power window motor is grounded through the DOWN contacts of the LH window switch to G204. The motor runs in order to drive the power window up. When a DOWN switch in the LH window switch is operated, the battery voltage is applied to the power window motor in the opposite direction. The power window motor is grounded through the UP contacts in the LH window switch to G204. The motor runs in order to drive the power window down.

The express down feature fully opens the left front power window automatically. This feature is activated by momentarily pressing the LH window switch past the first detent. If the UP button is pressed while the power window is in the express mode, the power window stops. When the express mode is activated, the LH window switch applies the voltage to the left front power window motor through the power window motor left front down control circuit (CKT 165 BRN). This action causes the motor to run. When the motor reaches the full-down position, a motor stall is detected by the LH window switch. This condition turns OFF the voltage to the motor.

Battery voltage is applied from the WINDOWS circuit breaker through the battery positive voltage circuit to the retained accessory power relay (RAP). The RAP relay supplies the voltage through the RAP relay switch supply voltage circuit and splice S322 to the RH window switch under the following conditions:

When the UP switch is pressed, the voltage is applied to one terminal of the power window motor through the power window motor right front up control circuit (CKT 666 DK BLU). Ground is applied to the opposite terminal of the power window motor from the LH window switch through the right front power window switch on the following circuits:

When the DOWN switch is pressed, the voltage is applied to one terminal of the power window motor through the power window motor right front down control circuit (CKT 667 BRN). Ground is applied to the opposite terminal of the power window motor from the LH window switch through the RH window switch on the following circuits:
