Pinpoint Test F: A Single Power Window is Inoperative - MKZ, RH Front

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

NOTE: A new RH front power window motor will not operate in one-touch up mode until initialized. Refer to Window Motor Initialization .

NOTE: The RH front power window motor must be initialized whenever a new motor is installed.

NOTE: The RH front power window motor must be de-initialized, then initialized whenever the RH front window motor is removed from the window regulator drum housing, a new window regulator is installed, a new window glass is installed, a new top run is installed or for any operation in which grease or lubricants are applied to the window regulator or glass run.

Normal Operation

Under normal operation, the LH and RH front power window control switches receive power from the accessory delay relay through circuit CBP41 (BU). The RH window motor receives battery power through circuit SBP04 (GN/RD) at all times and ground through circuit GD139 (BK/YE). When the LH or RH front window control switch is pulled, a voltage signal is sent to the RH front window motor through circuit CPW13 (BN/YE) which causes the window to move upward. When the LH or RH front window control switch is pressed, a voltage signal is sent to the RH front window motor through circuit CPW12 (GN/OG) which causes the window to move downward.

This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- RH front window motor
- LH or RH front window control switch
- RH front window motor not initialized



PINPOINT TEST F: A SINGLE POWER WINDOW IS INOPERATIVE - MKZ, RH FRONT

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.

-------------------------------------------------
F1 CHECK THE LH FRONT WINDOW CONTROL SWITCH OPERATION


- Attempt to operate the RH window using the LH front power window control switch.
- Does the RH window operate when using the LH front power window control switch?

Yes
GO to F7.

No
GO to F2.

-------------------------------------------------
F2 CHECK THE POWER TO THE LH FRONT WINDOW CONTROL SWITCH


- Disconnect: LH Front Window Control Switch C535A.
- Ignition ON.
- Measure the voltage between LH front window control switch C535A-3, circuit CBP41 (BU), harness side and ground.




- Is the voltage greater than 10 volts?

Yes
GO to F3.

No
VERIFY Smart Junction Box (SJB) fuse 41 (15A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the Wiring Diagrams to identify the possible causes of the circuit short Diagrams By Number.
DE-INITIALIZE, then INITIALIZE the front window motor. REFER to Window Motor Initialization . TEST the system for normal operation.

-------------------------------------------------
F3 CHECK THE POWER TO THE WINDOW MOTOR


- Ignition OFF.
- Disconnect: RH Front Window Motor C623.
- Measure the voltage between RH front window motor C623-4, circuit SBP04 (GN/RD), harness side and ground.




- Is the voltage greater than 10 volts?

Yes
GO to F4.

No
VERIFY SJB fuse 4 (30A) is OK. If OK, REPAIR the circuit. DE-INITIALIZE then INITIALIZE the RH front window motor.

If not OK, REFER to the Wiring Diagrams to identify the possible causes of the circuit short Diagrams By Number. REFER to Window Motor Initialization . TEST the system for normal operation.

-------------------------------------------------
F4 CHECK THE RH FRONT WINDOW MOTOR GROUND


- Measure the resistance between RH front window motor C623-3, circuit GD139 (BK/YE), harness side and ground.




- Is the resistance less than 5 ohms?

Yes
GO to F5.

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

-------------------------------------------------
F5 CHECK THE LH FRONT WINDOW CONTROL SWITCH-TO-RH FRONT WINDOW MOTOR FEEDS


- Measure the resistance between RH front window motor C623-1, circuit CPW12 (GN/OG), harness side and LH front window control switch C535A-2, circuit CPW12 (GN/OG), harness side.




- Measure the resistance between RH front window motor C623-6, circuit CPW13 (BN/YE), harness side and LH front window control switch C535A-6, circuit CPW13 (BN/YE), harness side.




- Are the resistances less than 5 ohms?

Yes
GO to F6.

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

-------------------------------------------------
F6 CHECK THE LH FRONT WINDOW CONTROL SWITCH


- Carry out the LH front window control switch component test.

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

Yes
INSTALL a new RH front window motor. REFER to Window Regulator and Motor - Front Door Window Regulator and Motor - Front Door. INITIALIZE the RH front window motor. REFER to Window Motor Initialization . TEST the system for normal operation.

No
INSTALL a new LH front window control switch. REFER to Window Control Switch Service and Repair. INITIALIZE the RH front window motor. REFER to Window Motor Initialization . TEST the system for normal operation.

-------------------------------------------------
F7 CHECK CIRCUIT CBP02 (GN) FOR VOLTAGE


- Disconnect: RH Front Window Control Switch C624.
- Ignition ON.
- Measure the voltage between RH front window control switch C624-2, circuit CBP41 (BU), harness side and ground.




- Is the voltage greater than 10 volts?

Yes
GO to F8.

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

-------------------------------------------------
F8 CHECK THE LH FRONT WINDOW CONTROL SWITCH-TO-RH FRONT WINDOW CONTROL SWITCH CIRCUITS


- Ignition OFF.
- Disconnect: LH Front Window Control Switch C535A.
- Measure the resistance between RH front window control switch C624-5, circuit CPW12 (GN/OG), harness side and LH front window control switch C535A-2, circuit CPW12 (GN/OG), harness side.
