Glass, Frames and Mechanisms

Pinpoint Test L: All Passenger Power Windows are Inoperative - LH and RH Rear

Normal Operation

The LH and RH rear window control switches receive voltage from the LH front window control switch when the lock-out switch is in the UNLOCK position. Ground is also provided to the LH and RH rear window control switches from the LH front window control switch. The LH and RH rear window control switches transfer voltage and ground to the power window motor. Window direction is controlled by reversing polarity of the voltage and ground circuits being supplied to the power window motor.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- LH front window control switch

PINPOINT TEST L : ALL PASSENGER POWER WINDOWS ARE INOPERATIVE - LH AND RH REAR

NOTICE: 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.

L1 CHECK THE VOLTAGE TO THE LH REAR WINDOW CONTROL SWITCH

- Disconnect: LH Rear Window Control Switch C701.

- Ignition ON.

- NOTE: Set the LH front window lock-out switch to the UNLOCK position.
Measure the voltage between LH rear window control switch C701-2, circuit CPW14 (VT/WH), harness side and ground.






Is the voltage greater than 10 volts?

Yes
GO to L3.
No
GO to L2.

L2 CHECK THE WINDOW CONTROL SWITCH POWER CIRCUIT FOR AN OPEN

- Ignition OFF.

- Disconnect: LH Front Window Control Switch C535B.

- Measure the resistance between LH rear window control switch C701-2, circuit CPW14 (VT/WH), harness side and LH front window control switch C535B-4, circuit CPW14 (VT/WH), harness side.






Is the resistance less than 5 ohms?

Yes
INSTALL a new LH front window control switch. REFER to Window Control Switch - Front . TEST the system for normal operation.
No
REPAIR the circuit. TEST the system for normal operation.

L3 CHECK THE LH FRONT WINDOW CONTROL SWITCH GROUND CIRCUIT FOR AN OPEN

- Ignition OFF.

- Disconnect: LH Front Window Control Switch C535B.

- Measure the resistance between LH front window control switch C535B-3, circuit GD134 (BK/VT), harness side and ground.






Is the resistance less than 5 ohms?

Yes
INSTALL a new LH front window control switch. REFER to Window Control Switch - Front . TEST the system for normal operation.
No
REPAIR the circuit. TEST the system for normal operation.
