Pinpoint Test H: A Single Power Window is Inoperative - RH Rear Window
Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information Electrical Diagrams.
Normal Operation
The RH rear window control switch receives power from the master window control switch when the lock-out switch is in the UNLOCK position. Ground is provided to the RH rear window control switch through the master window control switch. The RH rear window control switch transfers power and ground to the RH rear 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 rear 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 rear window control switch to operate the RH rear 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 H : A SINGLE POWER WINDOW IS INOPERATIVE - RH REAR 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.
H1 CHECK THE RH REAR WINDOW OPERATION FROM THE MASTER WINDOW CONTROL SWITCH
- Ignition ON.
- Operate the RH rear window from the master window control switch.
Does the RH rear window operate from the master window control switch?
Yes
GO to H2.
No
GO to H3.
H2 CHECK FOR VOLTAGE TO THE RH REAR WINDOW CONTROL SWITCH
- Ignition OFF.
- Disconnect: RH Rear Window Control Switch C801.
- Ignition ON.
- NOTE: Make sure the window lock-out switch is in the UNLOCK position.
Measure the voltage between RH rear window control switch C801-2, circuit CPW01 (BN/BU), harness side and ground.
Is the voltage greater than 10 volts?
Yes
INSTALL a new RH rear 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.
H3 CHECK FOR VOLTAGE AND GROUND TO THE WINDOW MOTOR
- Ignition OFF.
- Disconnect: RH Rear Power Window Motor C803.
- 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 rear power window motor C803-1, circuit CPW24 (WH/VT), harness side and RH rear power window motor C803-2, circuit CPW23 (GY), 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 rear window regulator motor. REFER to Window Regulator Motor - Rear Door Window Regulator Motor - Rear Door. TEST the system for normal operation.
No
GO to H4.
H4 CHECK THE RH REAR WINDOW CONTROL SWITCH
- Ignition OFF.
- Disconnect: RH Rear Window Control Switch C801.
- Carry out the window control switch component test on the RH rear window control switch.
Did the RH rear window control switch pass the component test?
Yes
GO to H5.
No
INSTALL a new RH rear window control switch. REFER to Window Control Switch Service and Repair. TEST the system for normal operation.
H5 CHECK FOR AN OPEN CIRCUIT BETWEEN THE REAR WINDOW CONTROL SWITCH AND THE WINDOW MOTOR
- Measure the resistance between RH rear window control switch C801, harness side and RH rear power window motor C803, harness side, using the following chart:
RH Rear Window Control Switch Circuit RH Rear Power Window Motor C801-1 CPW24 (WH/VT) C803-1 C801-7 CPW23 (GY) C803-2
Are the resistances less than 5 ohms?
Yes
GO to H6.
No
REPAIR the circuit(s). TEST the system for normal operation.
H6 CHECK FOR AN OPEN CIRCUIT BETWEEN THE RH REAR WINDOW CONTROL SWITCH AND THE MASTER WINDOW CONTROL SWITCH
- Disconnect: Master Window Control Switch C504C.
- Measure the resistance between master window control switch C504C, harness side and RH rear window control switch C801, harness side using the following chart:
Master Window Control Switch Circuit RH Rear Window Control Switch C504C-5 CPW17 (BN/GN) C801-3 C504C-6 CPW18 (GY/VT) C801-6
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.
