Pinpoint Test G: A Single Power Window Is Inoperative - Power Sliding Rear Window

WARNING: This page is about a different car, the 2012 Ford Pickup. 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.

G1 CHECK THE POWER WINDOW OPERATION
- Ignition ON.
- Verify the power windows operate.
- Do the power windows operate?
  - Yes : GO to G2.
  - No : GO to PINPOINT TEST B to diagnose the inoperative power windows.
G2 CHECK THE VOLTAGE TO THE OVERHEAD CONSOLE SWITCH
- Ignition OFF.
- Disconnect: Overhead Console Switch C912.
- Ignition ON.
- Measure the voltage between overhead console switch C912-1, circuit CBP01 (BU), harness side and ground.

- Is the voltage greater than 10 volts?
  - Yes : GO to G3.
  - No : REPAIR the circuit. TEST the system for normal operation.
G3 CHECK THE GROUND TO THE OVERHEAD CONSOLE SWITCH FOR AN OPEN
- Ignition OFF.
- Measure the resistance between overhead console switch C912-11, circuit GD139 (BK/YE), harness side and ground.

- Is the resistance less than 5 ohms?
  - Yes : GO to G4.
  - No : REPAIR the circuit(s). TEST the system for normal operation.
G4 CHECK THE OVERHEAD CONSOLE SWITCH
- Ignition ON.
- Connect a fused jumper between overhead console switch C912-1, circuit CBP01 (BU), harness side and C912-4, circuit CPW59 (VT/ BN), harness side; and a second fused jumper wire between overhead console switch C912-9, circuit CPW58 (YE/OG), harness side and C912-11, circuit GD139 (BK/YE), harness side. The power sliding window should open.

- Did the rear power sliding window open and close?
  - Yes : INSTALL a new overhead console control switch. TEST the system for normal operation.
  - No : GO to G5.

G5 CHECK THE POWER SLIDING WINDOW MOTOR CIRCUITS FOR AN OPEN

Disconnect: Power Sliding Window Motor C3145.

Measure the resistance between overhead console switch C912, harness side and power sliding window motor C3145, harness side using the following chart:

Overhead Console Switch	Circuit	Power Sliding Window Motor
C912-9	CPW58 (YE/OG)	C3145-2
C912-4	CPW59 (VT/BN)	C3145-1

Are the resistances less than 5 ohms?
- Yes : INSTALL a new rear sliding window motor. REFER to WINDOW REGULATOR MOTOR - REAR . TEST the system for normal operation.
- No : REPAIR the circuit(s). TEST the system for normal operation.
