Pinpoint Test F: A Single Power Window Is Inoperative - RH Rear

WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: 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 VOLTAGE TO THE RH REAR WINDOW CONTROL SWITCH
- Disconnect: RH Rear Window Control Switch C801 .
- Ignition ON.
- NOTE: Set the LH front window lock-out switch to the UNLOCK position.
  
  Measure the voltage between RH rear window control switch C801-2 , circuit CPW14 (VT/WH), harness side and ground.

Is the voltage greater than 10 volts?
- Yes : GO to F3.
- No : GO to F2 .
F2 CHECK THE WINDOW CONTROL SWITCH POWER CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: LH Front Window Control Switch C535B .
- Measure the resistance between RH rear window control switch C801-2 , 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.
F3 CHECK THE GROUNDS TO THE LH REAR WINDOW CONTROL SWITCH
- Ignition OFF.
- Measure the resistance between RH rear window control switch C801-1 , circuit CPW18 (GY/VT), harness side and ground; and between RH rear window control switch C801-3 , circuit CPW17 (BN/GN), harness side and ground.

Are the resistances less than 5 ohms?
- Yes : GO to F5.
- No : GO to F4 .

F4 CHECK CIRCUITS CPW17 (BN/GN) AND CPW18 (GY/VT) FOR AN OPEN

Disconnect: LH Front Window Control Switch C535B .

Measure the resistance between RH rear window control switch C801 , harness side and LH front window control switch C535B , harness side using the following chart:

RH Rear Window Control Switch	Circuit	LH Front Window Control Switch
C801-3	CPW17 (BN/GN)	C535B-4
C801-1	CPW18 (GY/VT)	C535B-7

Are the resistances 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(s). TEST the system for normal operation.

F5 CHECK THE RH REAR WINDOW OPERATION
- Ignition ON.
  NOTE: Set the LH front window lock-out switch to the UNLOCK position.
- Connect a fused jumper wire between RH rear window control switch C801-2 , circuit CPW14 (VT/WH), harness side and C801-6 , circuit CPW23 (GY), harness side; and a second fused jumper wire between RH rear window control switch C801-4 , circuit CPW24 (WH/VT), harness side and C801-1 , circuit CPW18 (GY/VT), harness side. The RH rear window should operate in the downward direction.

Does the LH rear window operate correctly?
- Yes : If the RH rear window did not operate with the RH rear window control switch, INSTALL a new RH rear window control switch. REFER to WINDOW CONTROL SWITCH - REAR .
  TEST the system for normal operation.
  
  If the RH rear window did operate with the RH rear window control switch, but not with the LH front window control switch, INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH - FRONT . TEST the system for normal operation.
- No : GO to F6 .

F6 CHECK THE POWER WINDOW MOTOR CIRCUITS FOR AN OPEN

Ignition OFF.
Disconnect: RH Rear Power Window Motor C828 (Super Cab) or C803 (Super Crew).

For Super Cab, measure the resistance between RH rear window control switch C801 , harness side and RH rear power window motor C828 , harness side using the following chart:

RH Rear Window Control Switch	Circuit	RH Rear Power Window Motor
C801-6	CPW23 (GY)	C828-1
C801-4	CPW24 (WH/VT)	C828-2
