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

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

Normal Operation

The RH front window control switch receives delayed accessory power through circuit CPW14 (VT/WH) when the window lock switch on the LH front window control switch is set to the UNLOCK position, and the delayed accessory feature is active. When the RH front window control switch is pressed to the DOWN position, the RH front window control switch receives ground from the LH front window switch through circuit CPW13 (BN/YE). When operating the RH front window in the down direction, the RH front window control switch supplies power to the RH front window motor through circuit CPW19 (VT) and ground through circuit CPW20 (WH/OG).

When the RH front window control switch is pressed to the UP position, the RH front window control switch receives ground from the LH front window switch through circuit CPW12 (GN/OG). When operating the RH front window in the up direction, the RH front window control switch provides power to the RH front window motor through circuit CPW20 (WH/OG) and ground through circuit CPW19 (VT).

RH Front Window Operation From LH Front Switch

When the RH front power window is operated in the up direction from the LH front window control switch, power is sent to the RH front window control switch through circuit CPW13 (BN/YE), which transfers power to the RH front window motor through circuit CPW20 (WH/OG). Ground is provided to the RH front window switch through circuit CPW12 (GN/OG), which transfers ground to the RH front window motor through circuit CPW19 (VT).

When the RH front power window is operated in the down direction from the LH front window control switch, power is sent to the RH front window control switch through circuit CPW12 (GN/OG), which transfers power to the front window motor through circuit CPW19 (VT). Ground is provided to the RH front window switch through circuit CPW13 (BN/YE), which transfers ground to the RH front window motor through circuit CPW20 (WH/OG).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- LH front window control switch
- RH front window control switch
- RH front window motor



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

-------------------------------------------------
C1 CHECK THE RH FRONT POWER WINDOW MOTOR


- Disconnect: LH Front Window Control Switch C504a and C504b.
- Ignition ON.
- Connect a fused jumper wire between LH front window control switch C504b-1, circuit CPW13 (BN/YE), harness side and LH front window control switch C504a-5, circuit CBP47 (GN/BU), harness side. Connect a second fused jumper wire between LH front window control switch C504b-5, circuit CPW12 (GN/OG) and LH front window control switch C504b-4, circuit GD133 (BK). The RH front window should operate in the upward direction.




- Connect a fused jumper wire between LH front window control switch C504b-5, circuit CPW12 (GN/OG), harness side and LH front window control switch C504a-5, circuit CBP47 (GN/BU), harness side. Connect a second fused jumper wire between LH front window control switch C504b-1, circuit CPW13 (BN/YE) and LH front window control switch C504b-4, circuit GD133 (BK). The RH front window should operate in the downward direction.




- Does the RH front window operate correctly?

Yes
GO to C2.

No
GO to C4.

-------------------------------------------------
C2 CHECK CIRCUIT CPW14 (VT/WH) FOR VOLTAGE


- Ignition OFF.
- Connect: LH Front Window Control Switch C504a and C504b.
- Disconnect: RH Front Window Control Switch C604.
- Ignition ON.
- NOTE: Be sure the window lock switch is set to the UNLOCK position.
- Measure the voltage between RH front window control switch C604-5, circuit CPW14 (VT/WH), harness side and ground.




- Is the voltage greater than 10 volts?

Yes
GO to C3.

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

-------------------------------------------------
C3 CHECK THE LH FRONT WINDOW CONTROL SWITCH


- Ignition OFF.
- Disconnect: LH Front Window Control Switch.
- Carry out the LH Front Window Control Switch Component Test.

- Did the LH front window control switch pass the component test?

Yes
GO to C4.

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

-------------------------------------------------
C4 CHECK THE RH FRONT WINDOW CONTROL SWITCH


- Carry out the RH Front Window Control Switch Component Test.

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

Yes
GO to C5.

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

-------------------------------------------------
C5 CHECK CIRCUITS CPW13 (BN/YE) AND CPW12 (GN/OG) FOR AN OPEN


- Measure the resistance between RH front window control switch C604-1, circuit CPW13 (BN/YE), harness side and LH front window control switch C504b-1, circuit CPW13 (BN/YE), harness side.




- Measure the resistance between RH front window control switch C604-6, circuit CPW12 (GN/OG), harness side and LH front window control switch C504b-5, circuit CPW12 (GN/OG), harness side.




- Are the resistances less than 5 ohms?

Yes
GO to C6.

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

-------------------------------------------------
C6 CHECK CIRCUIT CPW19 (VT) AND CIRCUIT CPW20 (WH/OG) FOR AN OPEN


- Disconnect: RH Front Window Motor C608.
- Measure the resistance between RH front window control switch C604-3, circuit CPW19 (VT), harness side and RH front window motor C608-1, circuit CPW19 (VT), harness side.




- Measure the resistance between RH front window control switch C604-4, circuit CPW20 (WH/OG), harness side and RH front window motor C608-2, circuit CPW20 (WH/OG), harness side.




- Are both resistances less than 5 ohms?

Yes
INSTALL a new RH front window motor. REFER to Glass, Frames and Mechanisms - Exploded View, Front Door Glass, Frames and Mechanisms - Exploded View, Front Door and Window Regulator Motor Window Regulator Motor. TEST the system for normal operation.

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