Pinpoint Test E: A Single Power Window Is Inoperative - RH Front

Glass, Frames and Mechanisms

Pinpoint Test E: A Single Power Window is Inoperative - RH Front, MKX

NOTE: A new RH front window motor cannot operate in one-touch up or one-touch down mode until initialized. Refer to Window Motor Initialization Procedures.

NOTE: De-initialize, then initialize the front window motor when any of the following occur:
- the RH front window motor is removed from the window regulator drum housing
- a new window regulator and/or motor is installed
- a new window glass is installed
- a new top run is installed
- any operation in which grease or lubricants are applied to the window regulator or glass run

Normal Operation

Under normal operation, the accessory delay relay supplies voltage to the RH front window motor and LH and RH front window control switches. The RH front window motor has dedicated high current voltage and ground circuits. When the LH or RH front window control switch is activated, a low current voltage signal is supplied to the RH front window motor which causes the window to move upward or downward. When the LH or RH front window control switch is pressed or pulled to the second detent position (AUTO), the LH/RH front window control switch also provides a ground signal to the RH front window motor to request the one-touch up/down operation.

This pinpoint test is intended to diagnose the following:

- Fuse

- Wiring, terminals or connectors

- Window control switch

- Power window motor

PINPOINT TEST E : A SINGLE POWER WINDOW IS INOPERATIVE - RH FRONT, MKX

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.

If not OK, REFER to the Wiring Diagrams to identify the possible causes of the circuit short [1][2]Diagrams By Number. REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RH front window motor. REFER to Window Motor Initialization Procedures. TEST the system for normal operation.

E4 CHECK THE MOTOR GROUND CIRCUIT

- Measure the resistance between RH front window motor C646-4, circuit GD140 (BK/GN), harness side and ground.






Is the resistance less than 5 ohms?

Yes
GO to E5.

No
REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RH front window motor. REFER to Window Motor Initialization Procedures. TEST the system for normal operation.

E5 CHECK THE LH FRONT WINDOW CONTROL SWITCH TO RH FRONT WINDOW MOTOR FEEDS
