Pinpoint Test C: All Passenger Power Windows are Inoperative - Fusion, Milan, LH and RH Rear

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

Normal Operation

Under normal operation, the accessory delay relay supplies voltage to the master window control switch. When the master window lockout control switch is in the UNLOCK position, voltage is supplied to the LH and RH rear window control switches. The master window control switch supplies the ground circuit for passenger rear window operation.

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


PINPOINT TEST C: ALL PASSENGER POWER WINDOWS ARE INOPERATIVE - FUSION, MILAN, LH AND RH REAR

NOTICE: 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.

-------------------------------------------------
C1 CHECK THE REAR PASSENGER WINDOW OPERATION FROM THE MASTER WINDOW CONTROL SWITCH

- Ignition ON.
- Attempt to operate the rear passenger windows from the master window control switch.
- Do the rear passenger windows operate from the master window control switch?

Yes
GO to C3.

No
GO to C2.

-------------------------------------------------
C2 CHECK THE MASTER WINDOW CONTROL SWITCH GROUND CIRCUIT FOR AN OPEN

- Ignition OFF.
- Disconnect: Master Window Control Switch C535B (if RH front window is equipped with one-touch up/down) or C537B (if RH front window is not equipped with one-touch up/down).
- Measure the resistance between master window control switch C535B-6 or C537B-7, circuit GD126 (BK/WH), harness side and ground.




- Is the resistance less than 5 ohms?

Yes
INSTALL a new master 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 MASTER WINDOW CONTROL SWITCH

- Carry out the master window control switch component test.

- Did the master window control switch pass the component test?

Yes
REPAIR circuit CPW14 (VT/WH) for an open. TEST the system for normal operation.

No
INSTALL a new master window control switch. REFER to Window Control Switch Service and Repair. TEST the system for normal operation.
