  1. At the driver's door, remove the power window/power mirror switch retaining screw.
  2. Lift up the power window switch so that the connector is exposed.
  3. Turn the ignition ON.
  4. Check the voltage at terminal A6 (ORN) of the power window switch.

Is the voltage equal to the specified value?		 11 - 14 V Go to Step 4 Go to Step 3
3 Repair the open power supply circuit to the driver's door power window switch.
Is the repair complete?		 - System OK -
4 Use an ohmmeter to check continuity between ground and terminal A10 (BLK) of the driver's door power window switch connector.
Does the ohmmeter indicate the specified value?		 ≈ 0 Ω Go to Step 6 Go to Step 5
5 Repair the open circuit between ground and terminal A10 (BLK) of the driver's door power window switch.
Is the repair complete?		 - System OK -
6 Replace the driver's door power window switch.
Is the repair complete?		 - System OK -

  4. Disconnect the 2-wire connector that connects the window motor to the door harness.
  5. Connect the negative jumper wire to one of the terminals of the 2-wire connector.
  6. Touch the positive jumper wire to the other terminal of the 2-wire connector.
  7. Reverse the jumper wire connections.

Does the window move up when the motor is powered directly by the battery, and down when the jumper connections are reversed?		 - Go to Step 9 Go to Step 8
8 Replace the window motor.
Is the repair complete?		 - System OK -
9 Check the operation of the windows.
Is the driver's window the one that is inoperative?		 - Go to Step 10 Go to Step 11

11
  1. Make sure the window lock switch on the driver's door is not engaged.
  2. Turn the ignition ON.
  3. Backprobe to check the voltage at terminal A9 (PNK/BLK) of the driver's door power window switch.

Is the voltage equal to the specified value?		 11 - 14 V Go to Step 12 Go to Step 10
12
  1. Make sure the window lock switch on the driver's door is not engaged.
  2. Turn the ignition ON.
  3. Check the voltage at terminal A9 (PNK/BLK) of the window switch connector for the inoperative window.

Is the voltage equal to the specified value?		 11 - 14 V Go to Step 14 Go to Step 13
13 Repair the open (PNK/BLK) wire between the window switch and the driver's door power window switch.
Is the repair complete?		 - System OK -
14
  1. At the inoperative window switch, use an ohmmeter to check continuity between ground and terminal B2.
  2. At the inoperative window switch, use an ohmmeter to check continuity between ground and terminal A10.

When performing both ohmmeter tests, does the ohmmeter indicate the specified value?		 ≈ 0 Ω Go to Step 15 Go to Step 16
15 Replace the power window switch.
Is the repair complete?		 - System OK -
16 If one of the window switch wires tested in Step 15 does not show continuity with ground, use an ohmmeter to test the continuity of that wire between the window switch and the driver's door power window switch.
Does the ohmmeter indicate the specified value?		 ≈ 0 Ω Go to Step 17 Go to Step 18
17 Replace the window switch for the inoperative window.
Is the repair complete?		 - System OK -
18 Repair the open circuit between the window switch and the driver's door power window switch.
