Power Windows Circuit Description Coupe

Battery voltage is applied from the PWR WDO circuit breaker through CKT 141 (BRN) to the power window switch terminal F and to terminal C of the power window control module. Ground for the power window switch is supplied through CKT 250 to terminal A.

When the power window switch down position is pressed, voltage is supplied to terminal B of the power window switch through CKT 501 to terminal E of the power window control module. If the power window switch is pressed for less than .3 seconds, the power window control module internal relay does not energize and passes the voltage through the switch side of the relay to terminal D of the power window control module. Voltage is then applied through CKT 167 to terminal B of the RH power window motor. With the power window switch down position pressed, ground for the power window motor is supplied from CKT 250 (terminal A) of the power window switch, through the up position switch to terminal C of the power window switch through CKT 166 to terminal A of the RH power window motor. With voltage at terminal B and ground at terminal A, the RH power window motor runs causing the window to travel down.

When the power window switch up position is pressed, voltage is supplied to terminal C of the power window switch through CKT 166 to terminal A of the RH power window motor. With the power window switch up position pressed, ground for the power window motor is supplied from CKT 250 (terminal A) of the power window switch, through the down position switch to terminal B of the power window switch through CKT 501 to terminal E of the power window control module. Ground is then supplied to terminal D of the power window control module through CKT 167 to terminal B of the RH power window motor. With voltage at terminal A and ground at terminal B, the RH power window motor runs in the opposite direction causing the window to travel up.

The express down feature fully opens the RH power window automatically. This feature is activated by pressing the RH window switch for more than .3 seconds. When the down switch is pressed, the power window control module senses the time duration of the switch being pressed and also the window motor current. Pressing the switch for more than .3 seconds energizes the internal relay in the power window control module. When the express mode is activated, the power window control module applies voltage to the RH power window motor through CKT 167 (TAN). Ground for the motor is supplied through CKT 166 through the up position switch to CKT 250 (terminal A). This action causes the motor run and the window travels down until one of the following conditions occur:

When the LH power window switch up position is pressed, voltage is supplied to terminal E of the power window switch through CKT 164 to terminal B of the power window motor. Ground for the motor is supplied at terminal A through CKT 165 from the switch down position (terminal D). This action causes power window motor to run and the window travels up.

When the LH power window switch down position is pressed, voltage is supplied to terminal D of the power window switch through CKT 165 to terminal A of the power window motor. Ground for the motor is supplied at terminal B through CKT 164 from the switch up position (terminal E). This action causes the power window motor to travel in the opposite direction and the window travels down.

Power Windows Circuit Description Sedan

Battery voltage is applied from the PWR WDO circuit breaker through CKT 141 (BRN) to the following components:

Ground for the master power window switch is supplied through CKT 250 to terminal E.

When the master power window switch down position is pressed, voltage is supplied to terminal A of the master power window switch through CKT 501 to terminal E of the power window control module. If the power window switch is pressed for less than .3 seconds, the power window control module internal relay does not energize and passes the voltage through the switch side of the relay to terminal D of the power window control module. Voltage is then applied through CKT 167 to terminal B of the RF power window motor. With the power window switch down position pressed, ground for the power window motor is supplied from CKT 250 (terminal A) of the master power window switch, through the up position switch to terminal B of the master power window switch through CKT 166 to terminal A of the RF power window motor. With voltage at terminal B and ground at terminal A, the RF power window motor runs causing the window to travel down.

When the master power window switch up position is pressed, voltage is supplied to terminal B of the master power window switch through CKT 166 to terminal A of the RF power window motor. With the master power window switch up position pressed, ground for the power window motor is supplied from CKT 250 (terminal E) of the master power window switch, through the down position switch to terminal A of the master power window switch through CKT 501 to terminal E of the power window control module. Ground is then supplied to terminal D of the power window control module through CKT 167 to terminal B of the RF power window motor. With voltage at terminal A and ground at terminal B, the RF power window motor runs in the opposite direction causing the window to travel up.

The express down feature fully opens the RF power window automatically. This feature is activated by pressing the RF window switch for more than .3 seconds. When the down switch is pressed, the power window control module senses the time duration of the switch being pressed and also the window motor current. Pressing the switch for more than .3 seconds energizes the internal relay in the power window control module. When the express mode is activated, the power window control module applies voltage to the RF power window motor through CKT 167 (TAN). Ground for the motor is supplied through CKT 166 through the up position switch to CKT 250 (terminal E). This action causes the motor to run and the window travels down until one of the following conditions occur:

When the LF master power window switch up position is pressed, voltage is supplied to terminal D of the master power window switch through CKT 164 to terminal B of the power window motor. Ground for the motor is supplied at terminal A through CKT 165 from the switch down position (terminal C). This action causes power window motor to run and the window travels up.

When the LF master power window switch down position is pressed, voltage is supplied to terminal C of the power window switch through CKT 165 to terminal A of the power window motor. Ground for the motor is supplied at terminal B through CKT 164 from the switch up position (terminal D). This action causes the power window motor to travel in the opposite direction and the window travels down.

The passenger window lockout switch is used to disable the use of the rear power window switches. Battery voltage to the lockout switch is supplied through CKT 141 to terminal A. The lockout switch opens or closes CKT 1307 to terminal F of each rear power window switch.

The LR window can be operated from either the master power window switch or from the left rear power window switch. When the LR up switch is pressed, voltage is supplied to the power window motor through CKT 668 to terminal B. When the LR master up switch is pressed, voltage is supplied to the power window motor through CKT 168 (terminal K) through the LR switch through CKT 668 to terminal B. Ground is supplied at terminal A of the power window motor through the LR down switch and through the master down switch (CKTs 669, 169 and 250).

When the LR down switch is pressed, voltage is supplied to the power window motor through CKT 669 to terminal A. When the LR master up switch is pressed, voltage is supplied to the power window motor through CKT 169 (terminal J) through the LR switch through CKT 669 to terminal A. Ground is supplied at terminal B of the power window motor through the LR up switch and through the master up switch (CKTs 668, 168 and 250).

The RR window can be operated from either the master power window switch or from the right rear power window switch. When the RR up switch is pressed, voltage is supplied to the power window motor through CKT 670 to terminal A. When the RR master up switch is pressed, voltage is supplied to the power window motor through CKT 170 (terminal H) through the RR switch through CKT 670 to terminal A. Ground is supplied at terminal B of the power window motor through the RR down switch and through the master down switch (CKTs 671, 171 and 250).

When the RR down switch is pressed, voltage is supplied to the power window motor through CKT 671 to terminal B.
