Pinpoint Test C: A Single Power Window is Inoperative - Rear Quarter
Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information. Diagrams By Number
Normal Operation
The quarter window motors receive voltage at all times through circuit 1773 (RD/LB) (LH) and 1670 (BN/YE) (RH). With the key in the ON position (or with the accessory delay relay active), the quarter window motors receive voltage through circuit 882 (BN/YE)/193 (YE/LG) (LH) and 882 (BN/YE) (RH). Ground is provided to the quarter window motors through circuit 1205 (BK).
When the window control switch is pulled up, voltage is supplied to the LH/RH quarter window motors through circuit 884 (YE/BK) to command the windows up. When the window control switch is pushed, voltage is supplied to the LH/RH quarter window motors through circuit 885 (YE/LB) to command the windows down.
The Smart Junction Box (SJB) disables/inhibits the rear quarter window control switch from operating the rear quarter windows when the convertible top ajar switch indicates the convertible top is not in the full UP or full DOWN position.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Rear window control switch
- Window motor
- SJB
PINPOINT TEST C: A SINGLE POWER WINDOW IS INOPERATIVE - REAR QUARTER
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: If SJB on-demand DTC B1141 or B1142 is present, the rear quarter windows may still function during convertible top operation, but will not function when commanded by the window control switch. Refer to the Smart Junction Box (SJB) DTC Chart for diagnosis. Diagnostic Trouble Code Tests and Associated Procedures
