Rear Window -- Left
CIRCUIT OPERATIONWhen the DRIVER selects window DOWN operation, power is supplied on the F81 circuit through the switch to circuit Q27. Circuit Q27 connects the drivers door switch to the left rear door switch. Power is passed through this switch to circuit Q23. The Q23 circuit then goes to the left rear window motor.
Ground for the window motor is supplied on the Q13 circuit back to the left rear door switch. Circuity internal to the switch then passes the ground to circuit Q17. Circuit Q17 connects the right front door switch to the master switch. A bus bar, internal to the switch, connects the Q17 circuit to the Z1 ground circuit.
For window UP operation the circuits are reversed. Circuits Q17 and Q13 are the feeds, and circuits Q23 and Q27 are the grounds.
If the switch is being operated from the LEFT REAR door, and the operator is requesting window DOWN operation, power is supplied on the Q1 circuit from the driver's master switch circuit through the switch to the Q23 circuit.
Ground for the motor is supplied on the Q13 circuit through the switch and back to the master switch on circuit Q17. A bus bar, internal to the switch, connects the Q17 circuit to the Z1 ground circuit.
For window UP operation, the circuits are reversed. Circuit Q13 is the power and circuit Q23 is the ground.
