Pinpoint Test B: A Single Power Window is Inoperative - RH Front
Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information [1][2]Diagrams By Number.
Normal Operation
Under normal operation, the RH front power window motor receives high current power at all times through circuit SBB29 (GY/RD). Ground is provided to the RH front power window motor through circuit GD139 (BK/YE). The RH front power window motor receives low current power from the accessory delay relay through circuit CBP41 (BU). Voltage is supplied to the LH and RH front window control switch through circuit CBP41 (BU). When the LH front 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 RH front or LH front window control switch is operated in the DOWN position, the RH front window motor receives a voltage signal through circuit CPW12 (GN/OG).
This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Window control switch
- Window motor
PINPOINT TEST B : A SINGLE POWER WINDOW IS INOPERATIVE - RH FRONT
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

Is the resistance less than 5 ohms?
Yes
GO to B7.
No
REPAIR the circuit. DE-INITIALIZE then INITIALIZE the RH front window motor. REFER to Window Motor Initialization . TEST the system for normal operation.
B7 CHECK THE LH FRONT WINDOW CONTROL SWITCH
- Ignition ON.
- 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 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 . DE-INITIALIZE then INITIALIZE the RH front window motor. REFER to Window Motor Initialization . TEST the system for normal operation.
B8 CHECK THE POWER TO THE RH FRONT WINDOW CONTROL SWITCH
