Pinpoint Test H: The One-Touch Up/Down Feature Is Inoperative

WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: 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.

H1 CHECK FOR POWER (B+) LOSS DURING LH OR RH FRONT WINDOW OPERATION
- Verify if power (B+) was lost during LH or RH front window operation.

Was power (B+) lost while LH or RH front window was in operation?

Yes : RAISE the LH or RH front window to the fully CLOSED position. VERIFY the window glass stalls into the upper header seal. The front window should function normally. TEST the system for normal operation.
No : GO to H2 .
H2 DE-INITIALIZE, THEN INITIALIZE THE FRONT MOTOR
- De-initialize the front window motor, then carry out the front window motor initialization procedure. Refer to WINDOW MOTOR INITIALIZATION .

Is the one-touch down feature operating correctly?

Yes : The system is operating normally at this time. The front window motor lost initialization.
No : For LH window, GO to H3 .
For RH window (MKX only), GO to H5.
H3 CHECK THE LH FRONT WINDOW CONTROL SWITCH
- Ignition OFF.
- Disconnect: LH Front Window Control Switch C535A and C535B (MKX) or C504A and C504B (Edge).
- Carry out the LH front window control switch component test.
  Refer to OEM WIRING DIAGRAMS COMPONENT TESTING .

Did the LH front window control switch pass the component test?

Yes : GO to H4 .
No : INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH .
TEST the system for normal operation.
H4 CHECK THE AUTO CIRCUIT FOR AN OPEN
- Disconnect: LH Front Window Motor C540.
- Measure the resistance between LH front window motor connector C540-2 , circuit CPW29 (VT/GY), harness side and LH front window control switch C535A-8 (MKX) or C504A-7 (Edge), circuit CPW29 (VT/GY), harness side.

Is the resistance less than 5 ohms?

Yes : INSTALL a new LH front window motor. REFER to WINDOW REGULATOR MOTOR . TEST the system for normal operation.
No : REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the LH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
H5 CHECK THE LH AND RH FRONT WINDOW CONTROL SWITCH
- Ignition OFF.
- Disconnect: LH Front Window Control Switch C535A, C535B and RH Front Window Control Switch C648.
- Carry out the LH and RH front window control switch component tests.
  Refer to OEM WIRING DIAGRAMS COMPONENT TESTING .

Did the LH and RH front window control switches pass the component tests?

Yes : GO to H6 .
No : INSTALL a new LH or RH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
H6 CHECK THE AUTO CIRCUIT FOR AN OPEN
- Disconnect: RH Front Window Motor C646.
- Measure the resistance between LH front window control switch C535A-1 , circuit CPW31 (GN/WH), harness side and RH front window motor connector C646-2 , circuit CPW31 (GN/WH), harness side; and between RH front window control switch C648-4 , circuit CPW31 (GN/WH), harness side and RH front window motor connector C646-2 , circuit CPW31 (GN/WH), harness side.

Is the resistance less than 5 ohms?

Yes : INSTALL a new RH front window motor. REFER to WINDOW REGULATOR MOTOR . TEST the system for normal operation.
No : REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
