REAR POWER VENT WINDOW MOTOR RH CIRCUIT CHECK
REAR POWER VENT WINDOW MOTOR RH CIRCUIT CHECK
DescriptionINFOID:0000000005147230
Rear power vent windows OPEN/CLOSE by receiving the signal from rear power vent window switch.
Diagnosis ProcedureINFOID:0000000005147231
Regarding Wiring Diagram information, refer to PWC-53, "Wiring Diagram".
1.CHECK REAR POWER VENT WINDOW SWITCH RH SIGNAL
1. Turn ignition switch OFF.
2. Disconnect rear power vent window motor RH.
3. Turn ignition switch ON.
4. Check voltage between rear power vent window motor LH con- nector B150 terminals 1, 2 and ground.
Is the inspection result normal?
YES >> Replace rear power vent window motor RH. Refer to GW-21, "Removal and Installation".
NO >> Repair or replace harness.
