NOTE: 

1. Turn the vehicle to the OFF (LOCK) mode.

2. Disconnect the front passenger's power window switch 24P connector.

Inspect the connector and socket terminals to be sure they are all making good contact:

Reconnect the 24P connector to the power window switch, do the following input tests:

Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained
14 GRN Under all conditions Measure the voltage to ground: There should be battery voltage. An open or high resistance in the wire
9 BLK In all power modes Measure the voltage to ground: There should be less than 0.2 V.
  • Poor ground (G405)
  • An open or high resistance in the ground wire

5. Turn the vehicle to the OFF (LOCK) mode. Disconnect the connector from the front passenger's power window switch, and do the following input tests:

NOTE:  After replacing the front passenger's power window switch, do the resetting the power window control unit .

Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained
15* 1*16* 1 YEL*PNK Vehicle ON mode, connect terminals No. 14 to No. 15 (or No. 16) and terminal No. 16 (or No. 15) to body ground with a jumper wires

NOTE:  if the mirror stops moving, disconnect battery power immediately.

Check the retract actuator operation: The right mirror should retract (or extend).
  • Faulty right retract actuator
  • An open or high resistance in the wire
6* 2 LT GRN Under all conditions, connect terminals No. 14 and No. 6 with a jumper wire Check the right power mirror defogger operation: The right power mirror defogger should work (the inside lower edge becomes warm).
  • Faulty right power mirror defogger
  • Poor ground (G405) or an open in the ground wire
  • An open or high resistance in the wire
17* 3*18* 3 WHT*BRN Under all conditions Connect terminals No. 14 and No. 17 (or No. 18), and terminals No. 18 (or No. 17) and No. 9 with jumper wires: The right power mirror should UP (or DOWN).
  • Faulty right power mirror actuator
  • Poor ground (G405) or an open in the ground wire
  • An open or high resistance in the wire
17* 3*20* 3 WHT*RED Under all conditions Connect terminals No. 14 and No. 17 (or No. 20), and terminals No. 20 (or No. 17) and No. 9 with jumper wires: The right power mirror should LEFT (or RIGHT).
  • Faulty right power mirror actuator
  • Poor ground (G405) or an open in the ground wire
  • An open or high resistance in the wire
24 GRY Disconnect these connectors:
  • Power window master switch 37P connector
  • Moonroof motor-control unit 14P connector* 4
Check for continuity between terminal No. 24 and power window master switch 37P connector terminal No. 36: There should be continuity. An open in the LIN(WINDOW) wire
Check for continuity between terminal No. 24 and moonroof motor-control unit 14P connector terminal No. 12: There should be continuity. An open in the LIN (WINDOW) wire
Check for continuity to ground: There should be no continuity. A short to ground in the LIN (WINDOW) wire

*1: With retractable mirror

*2: With mirror defogger

*3: Without DPMS
