Power Windows Acura RDX I

Scheme 1

Auto Reverse Operation

The system is composed of the power window master switch, the front passenger's power window switch, the driver's power window motor and the front passenger's power window motor.

The power window motor incorporates a pulser, which generates pulses during the motor's operation and sends the pulses to the power window control unit. As soon as the power window control unit detects no pulses from the pulser, the power window control unit makes the power window motor stop and reverse. If the window is more than halfway closed, it will reverse to the half open position. If the window is less than halfway closed, it will stop and reverse about 2 inches. This is to prevent pinching an obstacle during auto-up operation. The auto reverse operation is not active when the switch is held in the up position.

Resetting the Power Window Control Unit

Note. The clear procedure must be done prior to the learn procedure even if the auto function is working.

Resetting the driver's or passenger's power windows is required when any of the following have occurred

1. Power window control unit (built into the driver's master switch) is replaced
2. Power window regulator replacement or repair
3. Power window motor replacement or repair
4. Window run channel replacement or repair
5. Driver's or passenger's door glass replacement or repair
6. Power is removed from the power window control unit while the power window is moving.

Scheme 6

1. Turn the ignition switch ON (II)
2. Move the driver's or passenger's window all the way down by using the driver's window DOWN switch.
3. Open the driver's or front passenger's door. NOTE: Steps 4-7 must be done within 5 seconds of each other.
4. Turn the ignition switch OFF.
5. Push and hold the driver's or passenger's window DOWN switch.
6. Turn the ignition switch ON (II).
7. Release the driver's or passenger's window DOWN switch.
8. Repeat step 4-7 three more times.
9. Wait 1 second.
10. Confirm that AUTO UP and AUTO DOWN do not work. If AUTO UP and AUTO DOWN work, go back to step 1.
11. Move the driver's or passenger's window all the way down by using the driver's or passenger's window DOWN switch.
12. Pull up and hold the driver's or passenger's window UP switch until the window reaches the fully closed position, then continue to hold the switch for 1 second.
13. Confirm that the power window control unit is reset by using the driver's or passenger's window AUTO UP and AUTO DOWN functions. If the window still does not work in AUTO, repeat the procedure several times, paying close attention to the 5 second time limit between steps.

Power Window Master Switch Input Test

Note. The power window control unit is built into the power window master switch.

Scheme 7

1. Remove the power window master switch (A) (see «POWER WINDOW SWITCH REPLACEMENT»(/acura/rdx/i-2006-2009/remont/windows/#power-windows) ).
2. Reconnect the driver's door wire harness (B) to the driver's door sub harness (C).
3. Inspect the connector and socket terminals to be sure they are all making good contact. If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system. If the terminals look OK, make the following input tests at the connector. If a test indicates a problem, find and correct the cause, then recheck the system. If all the input tests prove OK, the power window master switch must be faulty; replace it.
4. With the master switch still disconnected, make these input tests at the connector. If any test indicates a problem, find and correct the cause, then recheck the system. If all the input tests prove OK, go to step 5.
