Pinpoint Test F: A Single Power Window is Inoperative - RH Front Window

Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information Electrical Diagrams.

Normal Operation

The RH front window control switch receives power from the Central Junction Box (CJB). Ground is provided to the RH front window control switch through the master window control switch. The RH front window control switch transfers power and ground to the RH front window motor. Window direction is controlled by reversing polarity of the voltage and ground circuits being supplied to the window motor.

When operating the RH front window from the master window control switch, power and ground is sent from the master window control switch through the normally closed contacts within the RH front window control switch to operate the RH front window. Window direction is controlled by reversing polarity of the voltage and ground circuits being supplied to the window motor.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Window control switch

- Window regulator motor

PINPOINT TEST F : A SINGLE POWER WINDOW IS INOPERATIVE - RH FRONT WINDOW

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.

F1 CHECK THE RH FRONT WINDOW OPERATION FROM THE MASTER WINDOW CONTROL SWITCH

- Ignition ON.

- Operate the RH front window from the master window control switch.

Does the RH front window operate from the master window control switch?

Yes
GO to F2.

No
GO to F3.

F2 CHECK FOR VOLTAGE TO THE RH FRONT WINDOW CONTROL SWITCH

- Ignition OFF.

- Disconnect: RH Front Window Control Switch C604.

- Ignition ON.

- Measure the voltage between RH front window control switch C604-2, circuit CBP34 (VT/BN), harness side and ground.





Is the voltage greater than 10 volts?

Yes
INSTALL a new RH front window control switch. REFER to Window Control Switch Service and Repair. TEST the system for normal operation.

No
REPAIR the circuit. TEST the system for normal operation.

F3 CHECK FOR VOLTAGE AND GROUND TO THE WINDOW MOTOR

- Ignition OFF.

- Disconnect: RH Front Power Window Motor C608.

- Ignition ON.

- NOTE: During the following step, the voltage being measured changes polarity dependent upon which direction the window control switch is activated.
Measure the voltage between RH front power window motor C608-1, circuit CPW19 (VT), harness side and RH front power window motor C608-2, circuit CPW20 (WH/OG), harness side while operating the master window control switch in the down then up positions.






Is the voltage greater than 10 volts when the window control switch is operated and 0 volt in the rest position?

Yes
INSTALL a new RH front window regulator motor. REFER to Window Regulator Motor - Front Door Window Regulator Motor - Front Door. TEST the system for normal operation.

No
GO to F4.

F4 CHECK THE RH FRONT WINDOW CONTROL SWITCH

- Ignition OFF.

- Disconnect: RH Front Window Control Switch C604.

- Carry out the window control switch component test on the RH front window control switch.

Did the RH front window control switch pass the component test?

Yes
GO to F5.

No
INSTALL a new RH front window control switch. REFER to Window Control Switch Service and Repair. TEST the system for normal operation.

F5 CHECK FOR AN OPEN CIRCUIT BETWEEN THE RH WINDOW CONTROL SWITCH AND THE WINDOW MOTOR

- Measure the resistance between RH front window control switch C604, harness side and RH front power window motor C608, harness side, using the following chart:

RH Front Window Control Switch Circuit RH Front Power Window Motor C604-1 CPW20 (WH/OG) C608-2 C604-7 CPW19 (VT) C608-1






Are the resistances less than 5 ohms?

Yes
GO to F6.

No
REPAIR the circuit(s). TEST the system for normal operation.

F6 CHECK FOR AN OPEN CIRCUIT BETWEEN THE RH WINDOW CONTROL SWITCH AND THE MASTER WINDOW CONTROL SWITCH

- Disconnect: Master Window Control Switch C504A.

- Measure the resistance between master window control switch C504A, harness side and RH front window control switch C604, harness side using the following chart:

Master Window Control Switch Circuit RH Front Window Control Switch C504A-1 CPW12 (GN/OG) C604-3 C504A-4 CPW13 (BN/YE) C604-6






Are the resistances less than 5 ohms?

Yes
INSTALL a new master window control switch. REFER to Window Control Switch Service and Repair. TEST the system for normal operation.

No
REPAIR the circuit(s). CARRY OUT the window motor initialization procedure. REFER to Window Motor Initialization Programming and Relearning. TEST the system for normal operation.
