   2. Disconnect rear power window switch connector.
   3. Turn ignition switch ON.
   4. Check voltage between rear power window switch harness connector and ground.

      (+)			(-)	Condition		Voltage (Approx.)
      Rear power window switch
      Connector		Terminal
      LH	D203	7	Ground	Power window main switch (rear LH)	NEUTRAL	0
      					DOWN	Battery voltage
      		8			NEUTRAL	0
      					UP	Battery voltage
      RH	D303	7		Power window main switch (rear RH)	NEUTRAL	0
      					DOWN	Battery voltage
      		8			NEUTRAL	0
      					UP	Battery voltage

      Is the inspection result normal? 

      YES: GO TO  3.

      NO: GO TO 2.

2. CHECK REAR POWER WINDOW SWITCH CIRCUIT 
   1. Turn ignition switch OFF.
   2. Disconnect power window main switch connector.
   3. Check continuity between power window main switch harness connector and rear power window switch harness connector.

      Power window main switch		Rear power window switch			Continuity
      Connector	Terminal	Connector		Terminal
      D7	1	LH	D203	8	Yes
      	3			7
      	5	RH	D303	7
      	7			8

   4. Check continuity between power window main switch harness connector and ground.

      Power window main switch		Ground	Continuity
      Connector	Terminal
      D7	1		No
      	3
      	5
      	7

      Is the inspection result normal? 

      YES: Replace power window main switch. Refer to "REMOVAL AND INSTALLATION ".

      NO: Repair or replace harness.

3. CHECK REAR POWER WINDOW SWITCH 

   Check rear power window switch.

   Refer to "COMPONENT INSPECTION ".

   Is the inspection result normal? 

   YES: Check intermittent incident. Refer to "INTERMITTENT INCIDENT ".

   NO: Replace rear power window switch. Refer to "REMOVAL AND INSTALLATION ".
