Pinpoint Test C: A Single Power Window is Inoperative - RF, Navigator
Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information. Diagrams By Number
Normal Operation
Under normal operation, the RF power window motor microprocessor receives power at all times through circuit SBP04 (GN/RD) and from the accessory delay relay through circuit CBP41 (BU). Ground is provided at all times through circuit GD138 (BK/WH). The master window control switch or passenger window control switch provides a voltage input to the power window motor microprocessor through circuit CPW19 (VT) to operate the RF window down, and voltage input through circuit CPW20 (WH/OG) to operate the RF window up.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Window control switch
- Front door window regulator motor
PINPOINT TEST C: A SINGLE POWER WINDOW IS INOPERATIVE - RF, NAVIGATOR
NOTE: The RF power window motor is not on the multiplex link.
NOTE: A new RF power window motor will not operate in one-touch up or one-touch down mode until initialized. Refer to Window Motor Initialization .
NOTE: The RF power window motor must be initialized whenever: the motor is removed from the window regulator drum housing, a new motor is installed, a new window regulator is installed, a new window glass is installed, a new top run is installed and any operation in which grease or lubricants are applied to the window system.
-------------------------------------------------
C1 CHECK THE MASTER WINDOW CONTROL SWITCH OPERATION
- Attempt to operate the RH window using the master window control switch.
- Does the RH window operate when using the master window control switch?
Yes
GO to C7.
No
GO to C2.
-------------------------------------------------
C2 CHECK THE POWER TO THE WINDOW MOTOR
