Pinpoint Test H : The Left Or Right Power Window Is Inoperative - Rear Vent Window: Notes

Refer to Power Windows , for schematic and connector information.

Normal Operation 

Under normal operation, the quarter window control switch, quarter window close relay and quarter window open relay receive power from the accessory delay relay through circuit CBP41 (BU)/CBP32 (GN/VT). Ground is provided to the quarter window close relay and quarter window open relay through circuit GD151 (BK/GN). Ground is provided to the quarter window control switch through GD138 (BK/WH). The quarter window control switch activates the quarter window open relay by supplying a ground input through circuit CPW26 (BU/BN) and activates the quarter window close relay by supplying a ground input through circuit CPW25 (YE/BU). When the quarter window open relay is activated, power is supplied to the LH and RH quarter window motors through circuit CPW27 (GN) and ground through circuit CPW28 (WH/BN) through the quarter window close relay circuit GD151 (BK/GN) to operate the quarter windows open. When the quarter window close relay is activated, power is supplied to the LH and RH quarter window motors through circuit CPW28 (WH/BN) and ground through circuit CPW27 (GN) through the quarter window open relay circuit GD151 (BK/GN) to operate the quarter windows closed.

This pinpoint test is intended to diagnose the following: 

• Quarter window close relay
• Quarter window open relay
• Wiring, terminals or connectors
• Quarter window control switch (part of the overhead console)
• Rear quarter window regulator motor
