Pinpoint Test E: A Single Power Window Is Inoperative - LH Or RH Rear

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

E1 CHECK THE VOLTAGE TO THE LH OR RH REAR WINDOW CONTROL SWITCH
- Disconnect: Inoperative Rear Window Control Switch C701 (LH) or C801 (RH).
- Ignition ON.
- For an inoperative LH rear window, measure the voltage between LH rear window control switch C701-3, circuit CPW14 (VT/WH), harness side and ground.
- For an inoperative RH rear window, measure the voltage between RH rear window control switch C801-3, circuit CPW14 (VT/WH), harness side and ground.

- Is the voltage greater than 10 volts?
- Yes : GO to E2.
- No : REPAIR the circuit. TEST the system for normal operation.
E2 CHECK THE GROUNDS TO THE INOPERATIVE REAR WINDOW CONTROL SWITCH
- Ignition OFF.
- For an inoperative LH rear window, measure the resistance between LH rear window control switch C701-6, circuit CPW16 (BU/OG), harness side and ground; and between LH rear window control switch C701-1, circuit CPW15 (YE), harness side and ground.
- For an inoperative RH rear window, measure the resistance between RH rear window control switch C801-6, circuit CPW18 (GY/VT), harness side and ground; and between RH rear window control switch C801-1, circuit CPW17 (BN/GN), harness side and ground.

Are the resistances less than 5 ohms?

Yes : GO to E4.
No : REPAIR the circuit(s). TEST the system for normal operation.

E4 CHECK THE INOPERATIVE WINDOW CONTROL SWITCH
NOTE: Set the window lock switch to the UNLOCK position.
- Ignition ON.
- For an inoperative RH rear window, connect a fused jumper wire between RH rear window control switch C801-1, circuit CPW17 (BN/GN) and RH rear window control switch C801-5, circuit CPW24 (WH/VT); and between RH rear window control switch C801-3, circuit CPW14 (VT/WH) and RH rear window control switch C801-2, circuit CPW23 (GY). The RH rear window should operate in the downward direction.
