Pinpoint Test C: All Passenger Power Windows are Inoperative - Fusion, Milan

Refer to Wiring Diagram Set 100 (Fusion/Milan/MKZ, Fusion Hybrid/Milan Hybrid), Power Windows for schematic and connector information. Diagrams By Number

Normal Operation

Under normal operation, the LH front window control switch receives power through circuit CBP47 (GN/BU), which is the accessory delay relay output from the Smart Junction Box (SJB). Ground is provided to the LH front window control switch through circuit GD126 (BK/WH). When the LH front window lockout switch is in the UNLOCK position, power is supplied to all passenger window control switches through circuit CPW14 (VT/WH).

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

GO to C3.

No
GO to C2.

-------------------------------------------------
C2 CHECK CIRCUIT GD126 (BK/WH) FOR AN OPEN


- Ignition OFF.
- Disconnect: LH Front Window Control Switch C537B.
- Measure the resistance between LH front window control switch C537B-7, circuit GD126 (BK/WH), harness side and ground.




- Is the resistance less than 5 ohms?

Yes
INSTALL a new LH front window control switch. REFER to Window Control Switch Service and Repair. TEST the system for normal operation.

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

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