Pinpoint Test C: A Single Power Window is Inoperative - Passenger Front
Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information. Diagrams By Number
Normal Operation
Voltage is supplied to the passenger front window control switch from the driver window control switch through circuit 170 (RD/LB). If the driver window control switch is in the LOCK position, the circuit is open and the window does not operate from the passenger front window control switch.
When operating the passenger front window in the down direction, ground is provided from the driver window control switch through circuit 313 (WH/YE). Voltage is supplied to the passenger front window motor through circuit 333 (YE/RD) and ground through circuit 334 (RD/YE).
When operating the passenger front window in the up direction, ground is received from the driver window control switch through circuit 314 (TN/LB). Voltage is supplied to the passenger front window motor through circuit 334 (RD/YE) and ground through circuit 333 (YE/RD).
When the passenger front window is operated in the down direction from the driver window control switch, voltage is sent to the passenger front window control switch through circuit 314 (TN/LB), which transfers voltage to the passenger front window motor through circuit 333 (YE/RD). Ground is provided to the RH front window switch through circuit 313 (WH/YE), which transfers ground to the passenger front window motor through circuit 334 (RD/YE). When the passenger front window is operated in the up direction from the driver window control switch, voltage is sent to the passenger front window control switch through circuit 313 (WH/YE), which transfers voltage to the passenger front window motor through circuit 334 (RD/YE). Ground is provided to the passenger front window switch through circuit 314 (TN/LB), which transfers ground to the passenger front window motor through circuit 333 (YE/RD).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Passenger window motor
- Passenger front window control switch
- Driver window control switch
PINPOINT TEST C: A SINGLE POWER WINDOW IS INOPERATIVE - PASSENGER FRONT
-------------------------------------------------
C1 CHECK THE OPERATION FROM THE DRIVER WINDOW CONTROL SWITCH
- Ignition ON.
- Operate the front passenger window from the driver window control switch.
- Does the front passenger window operate from the driver window control switch?
Yes
VERIFY the window lock button is off. If the button is off, GO to C10 .
No
GO to C2.
-------------------------------------------------
C2 CHECK THE DOWN INPUT TO THE WINDOW MOTOR
- Ignition OFF.
