Pinpoint Test E: A Single Power Window is Inoperative - MKZ, RH Front
Refer to Wiring Diagram Set 100, 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 or one-touch down 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 delay accessory relay through circuit CBP02 (GN). The RH window motor receives battery power through circuit SBB35 (BU/RD) at all times and ground through circuit GD139 (BK/YE). When the LH or RH front window control switch is operated in the UP position, the RH front window motor receives a voltage signal through circuit CPW13 (BN/YE). When the LH or RH front window control switch is operated in the DOWN position, the RH front window motor receives a voltage signal through circuit CPW12 (GN/OG). When the RH front window motor receives a ground signal on circuit CPW31 (GN/WH), the RH front window motor will enter one-touch up/down mode.
This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- RH front window motor
- LH or RH front window control switch
- RH front window motor not initialized
PINPOINT TEST E: A SINGLE POWER WINDOW IS INOPERATIVE - MKZ, RH FRONT
-------------------------------------------------
E1 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 E6.
No
GO to E2.
-------------------------------------------------
E2 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 SBB35 (BU/RD), harness side and ground.
- Is the voltage greater than 10 volts?
Yes
GO to E3.
No
VERIFY Battery Junction Box (BJB) fuse 35 (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. REFER to Window Motor Initialization . TEST the system for normal operation.
-------------------------------------------------
E3 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 E4.
No
REPAIR the circuit. DE-INITIALIZE then INITIALIZE the RH front window motor. REFER to Window Motor Initialization . TEST the system for normal operation.
-------------------------------------------------
E4 CHECK THE LH FRONT WINDOW CONTROL SWITCH-TO-RH FRONT WINDOW MOTOR FEEDS
- Disconnect: LH Front Window Control Switch C535A.
- 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 C623-5, circuit CPW31 (GN/WH), harness side and LH front window control switch C535A-1, circuit CPW31 (GN/WH), 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-5, circuit CPW13 (BN/YE), harness side.
- Are the resistances 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 . TEST the system for normal operation.
-------------------------------------------------
E5 CHECK THE LH FRONT WINDOW CONTROL SWITCH
- Carry out the Master Window Adjust Switch Component Test.
- Did the window control switch pass the component test?
Yes
INSTALL a new RH front window motor. REFER to Glass, Frames and Mechanisms - Exploded View, Front Door Glass, Frames and Mechanisms - Exploded View, Front Door and 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.
-------------------------------------------------
E6 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 CBP02 (GN), harness side and ground.
- Is the voltage greater than 10 volts?
Yes
GO to E7.
No
REPAIR the circuit. TEST the system for normal operation.
-------------------------------------------------
E7 CHECK THE LH FRONT WINDOW CONTROL SWITCH-TO-RH FRONT WINDOW CONTROL SWITCH CIRCUITS
