Pinpoint Test I: A Single Power Window is Inoperative - RH Front, LH or RH Rear




Glass, Frames and Mechanisms

Pinpoint Test I: A Single Power Window is Inoperative - Fusion, Milan, RH Front, LH or RH Rear

NOTE: To diagnose an inoperative RH front window that is equipped with one-touch up/down feature, GO to Pinpoint Test G. Pinpoint Test G: A Single Power Window is Inoperative - RH Front (RH Front Window is Equipped With One-Touch Up/Down)

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

The RH front window control switch receives voltage from the accessory delay relay. The LH and RH rear window control switches receive voltage from the LH front window control switch when the window lock switch is set to the UNLOCK position. Ground is provided to the RH front, LH rear and RH rear window control switches from the LH front window control switch. Each window control switch transfers voltage and ground to their respective window motors. Window direction is controlled by reversing polarity of the voltage and ground circuits being supplied to the window motor.

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


PINPOINT TEST I: A SINGLE POWER WINDOW IS INOPERATIVE - FUSION, MILAN, RH FRONT, LH OR 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.
