Front Window -- Left
CIRCUIT OPERATIONWhen the DRIVER selects window DOWN operation, power is supplied on the F81 circuit through the switch to circuit Q26. Circuit Q26 connects the drivers door switch to the left front door switch. Power is passed through this switch to circuit Q21. The Q21 circuit then goes to the left front window motor.
Ground for the window motor is supplied on the Q11 circuit back to the left front door switch. Circuity internal to the switch then passes the ground to circuit Q16. Circuit Q16 connects the left front door switch to the master switch. A bus bar, internal to the switch, connects the Q16 circuit to the Z1 circuit.
For window UP operation the circuits are reversed. Circuits Q16 and Q11 are the feeds, and circuits Q21 and Q26 are the grounds.
If the switch is being operated from the PASSENGER'S front 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 Q21 circuit.
Ground for the motor is supplied on the Q11 circuit through the switch and back to the master switch on circuit Q16. A bus bar, internal to the switch, connects the Q16 circuit to the Z1 circuit.
For window UP operation, the circuits are reversed. Circuit Q11 is the power and circuit Q21 is the ground.
