Pinpoint Test G: A Single Power Window Is Inoperative - RH Rear

NOTE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

G1 CHECK FOR VOLTAGE TO THE MASTER WINDOW CONTROL SWITCH

Ignition OFF.
Disconnect: RH Rear Window Control Switch C819.
Ignition ON.
Make sure the rear passenger window lock-out switch (located in the master window control switch assembly) is in the UNLOCK position.

Measure the voltage between:

Positive Lead		Negative Lead
Pin	Circuit	Pin	Circuit
C819-2	RPW09 (BN/WH)	-	Ground

Are the voltages greater than 11 volts?

Yes : GO to G2.
No : REPAIR the circuit.

G2 CHECK THE MASTER WINDOW CONTROL SWITCH NORMALLY CLOSED GROUND CIRCUITS FOR AN OPEN

Ignition OFF.

Measure the resistance between:

Positive Lead		Negative Lead
Pin	Circuit	Pin	Circuit
C819-3	CPW23 (GY)	-	Ground
C819-6	CPW24 (WH/VT)	-	Ground

Are the resistances less than 3 ohms?

Yes : GO to G4.
No : GO to G3.

G3 CHECK THE POWER WINDOW CONTROL CIRCUITS FOR AN OPEN

Disconnect: Master Window Control Switch C504C.

Measure the resistance between:

Positive Lead		Negative Lead
Pin	Circuit	Pin	Circuit
C504C-7	CPW18 (GY/VT)	C819-6	CPW24 (WH/VT)
C504C-6	CPW17 (BN/GN)	C819-3	CPW23 (GY)

Are the resistances less than 3 ohms?

Yes : INSTALL a new master window control switch. REFER to WINDOW CONTROL SWITCH - FRONT .
No : REPAIR the circuit in question.

G4 CHECK THE POWER WINDOW UPWARD AND/OR DOWNWARD OPERATION

Ignition ON.

To check downward window operation, momentarily connect fused jumper wires:

Lead		Lead
Pin	Circuit	Pin	Circuit
C819-2	RPW09 (BN/WH)	C819-7	CPW23 (GY)
C819-4	GD145 (BK/BU)	C819-1	CPW24 (WH/VT)

To check upward window operation, momentarily connect fused jumper wires:

Lead		Lead
Pin	Circuit	Pin	Circuit
C819-2	RPW09 (BN/WH)	C819-1	CPW24 (WH/VT)
C819-4	GD145 (BK/BU)	C819-7	CPW23 (GY)

Does the RH rear window move up and/or down?

Yes : REMOVE the jumper wires. If the RH rear window did not operate from the RH rear window control switch, INSTALL a new RH rear window control switch. REFER to WINDOW CONTROL SWITCH - REAR .
If the RH rear window did not operate from the master window control switch, INSTALL a new master window control switch. REFER to WINDOW CONTROL SWITCH - FRONT .
No : REMOVE the jumper wires, GO to G5.

G5 CHECK THE POWER WINDOW CIRCUITS FOR AN OPEN

Ignition OFF.
Disconnect: RH Rear Window Motor C803.

Measure the resistance between:

Positive Lead		Negative Lead
Pin	Circuit	Pin	Circuit
C819-1	CPW24 (WH/VT)	C803-1	CPW24 (WH/VT)
C819-7	CPW23 (GY)	C803-2	CPW23 (GY)

Are the resistances less than 3 ohms?

Yes : MAKE SURE there are no mechanical binding conditions preventing the glass mechanism from operating correctly. If a mechanical binding issue is found, REPAIR as necessary. If no mechanical binding condition exists, INSTALL a new RH rear power window motor. REFER to WINDOW REGULATOR - REAR DOOR .
No : REPAIR the circuit in question.
