Pinpoint Test A: A Single Power Window Is Inoperative - Power Sliding Window
WARNING: This page is about a different car, the 2009 Ford Pickup, 2009 Ford F550 Super Duty, 2009 Ford F450 Super Duty, and 2009 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
- A1 CHECK VOLTAGE TO THE POWER SLIDING WINDOW SWITCH
- Disconnect: Power Sliding Window Switch C203
- Key in ON position.
- Measure the voltage between power sliding window switch C203-3, circuit CBP47 (GN/BU) harness side and ground.
- Is the voltage greater than 10 volts?
- YES : Go to A2.
- NO : VERIFY smart junction box (SJB) circuit breaker 47 (30A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.
- A2 CHECK GROUND TO THE POWER SLIDING WINDOW SWITCH
- Key in OFF position.
- Measure the resistance between power sliding window switch C203-1, circuit GD115 (BK/GY) harness side and ground.
- Are the resistances less than 5 ohms?
- YES : Go to A3.
- NO : REPAIR the circuit(s). TEST the system for normal operation.
- A3 CHECK THE POWER SLIDING WINDOW SWITCH
- Key in ON position.
- Connect a 30A fused jumper between power sliding window switch C203-3, circuit CBP47 (GN/BU) and C203-2, circuit CPW58 (YE/OG) harness side; and between power sliding window switch C203-5, circuit CPW59 (VT/BN) and C203-1, circuit GD115 (BK/GY) harness side. The power sliding window should open.
- Connect a 30A fused jumper between power sliding window switch C203-3, circuit CBP47 (GN/BU) and C203-5, circuit CPW59 (VT/BN) harness side; and between power sliding window switch C203-2, circuit CPW58 (YE/OG) and C203-1, circuit GD115 (BK/GY) harness side. The power sliding window should close.
- Did the power sliding window open and close?
- YES : INSTALL a new power sliding window switch. TEST the system for normal operation.
- NO : Go to A4.
- A4 CHECK CIRCUIT CPW58 (YE/OG) AND CIRCUIT CPW59 (VT/BN) FOR AN OPEN
- Key in OFF position.
- Disconnect: Power Sliding Window Motor C301
- Measure the resistance between power sliding window motor C301-1, circuit CPW58 (YE/OG) and power sliding window switch C203-2, circuit CPW58 (YE/OG) harness side; and between power sliding window motor C301-2, circuit CPW59 (VT/BN) and power sliding window switch C203-5, CPW59 (VT/BN) harness side.
- Are the resistances less than 5 ohms?
- YES : INSTALL a new rear window motor. TEST the system for normal operation.
- NO : REPAIR the circuit(s). TEST the system for normal operation.
