Pinpoint Test F: A Single Power Window Is Inoperative - LH (Left-Hand) Rear

NOTE: If both rear windows are inoperative, GO to Pinpoint Test C

Refer to POWER WINDOWS for schematic and connector information.

Normal Operation and Fault Conditions

REFER to: Glass, Frames and Mechanisms - Vehicles With: One-Touch Open Driver Window - System Operation and Component Description .

Possible Sources
- Wiring, terminals or connectors
- Master window control switch
- LH rear window control switch
- LH rear window regulator motor
Visual Inspection and Pre-checks
- Verify the lock-out switch is in the UNLOCK position.

F1 CHECK THE VOLTAGE TO THE INOPERATIVE REAR WINDOW CONTROL SWITCH

Ignition OFF.

Disconnect: Rear Window Control Switch LH C717.

Ignition ON.

Make sure the rear passenger window lock-out switch (located in the master window control switch) is in the UNLOCK position.

Yes

GO to F2

No	REPAIR the circuit.

F2 CHECK THE MASTER WINDOW CONTROL SWITCH NORMALLY CLOSED GROUND CIRCUITS FOR AN OPEN

Ignition OFF.

Are the resistances less than 3 ohms?

Yes

GO to F4

GO to F3

F3 CHECK THE POWER WINDOW CONTROL CIRCUITS FOR AN OPEN

Disconnect: Master Window Control Switch C504C.

Measure:

Are the resistances less than 3 ohms?

Yes	INSTALL a new master window control switch. REFER to: Front Door Window Control Switch .

No	REPAIR the circuit in question.

F4 CHECK THE LH (LEFT-HAND) REAR POWER WINDOW UPWARD AND/OR DOWNWARD OPERATION

Ignition ON.

To check downward window operation, connect fused jumper wires:

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

Yes

REMOVE the jumper wires. If the rear window did not operate from the rear window control switch, INSTALL a new LH rear window control switch. If the rear window did not operate from the master window control switch, INSTALL a new master window control switch. REFER to: Front Door Window Control Switch .

No	REMOVE the jumper wires. GO to F5

F5 CHECK THE LH (LEFT-HAND) REAR POWER WINDOW CIRCUITS FOR AN OPEN

Ignition OFF.

Disconnect: LH Rear Power Window Motor C703.

Measure:

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 LH rear window regulator motor.

No	REPAIR the circuit in question.
