• If the terminals are bent, loose or corroded, repair them as necessary and recheck the system.
• If the terminals look OK, go to step 5.

• 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 6.
  TROUBLE SYMPTOMS CHART
  
  

  Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
  37	BLK	In all ignition switch positions	Measure the voltage to ground: There should be less than 0.5 V.	Poor ground (G505) or an open in the ground wire An open or high resistance in the wire
  25	GRN	Under all conditions	Measure the voltage to ground: There should be battery voltage.	Blown No. 13 (20 A) fuse in the passenger's under-dash fuse/relay box Faulty driver's under-dash fuse/relay box Faulty passenger's under-dash fuse/relay box An open or high resistance in the wire
  26(1)	PUR	Ignition switch ON (II)	Measure the voltage to ground: There should be battery voltage.	Faulty front passenger's power window switch A short to ground in the wire
  27(1)	PNK	Ignition switch ON (II), and front passenger's power window switch moving up or down	Measure the voltage between terminals No. 27 and No. 37: An analog voltmeter should alternate between 0 V and about 5 V (a digital voltmeter should read about 2.5 V while the window moves).	Faulty front passenger's power window switch Faulty front passenger's power window motor An open or high resistance in the wire A short to ground in the wire
  28(1)	ORN	Ignition switch ON (II), and front passenger's power window switch moving up or down	Measure the voltage between terminals No. 28 and No. 37: An analog voltmeter should alternate to between 0 V and about 5 V (a digital voltmeter should read about 2.5 V while the window moves).	Faulty front passenger's power window switch Faulty front passenger's power window motor An open or high resistance in the wire A short to ground in the wire
  36(1)	BLK	Under all conditions, disconnect the front passenger's power window motor 6P Connector.	Check for continuity to ground: There should be continuity.	Poor ground(G505) or an open in the ground wire An open or high resistance in the wire

• If any test indicates a problem, find and correct the cause, then recheck the system.
• If all the input tests prove OK, replace the front passenger's power window switch, then go to step 9.

    Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
    12	BLU	Under all conditions, connect terminals No. 25 and No. 24 (or No. 12), and terminals No. 12 (or No. 24) and No. 37 with jumper wires.	Check front passenger's power window motor operation: The front passenger's power window should open (or close).	Faulty front passenger's power window motor An open or high resistance in the wire
    24	RED
    29	BLU	Disconnect the power window master switch 37P Connector and moonroof control unit/motor 14P Connector.	Check for continuity between terminal No. 29 and power window master switch 37P Connector terminal No. 27: There should be continuity.	An open in the UART wire
    			Check for continuity between terminal No. 29 and moonroof control unit/motor 14P Connector terminal No. 11: There should be continuity.	An open in the UART wire
    			Check for continuity to ground: There should be no continuity.	A short to ground in the UART wire
