CIRCUIT OPERATION
When the DRIVER selects window DOWN operation power is supplied on the F21 circuit through the switch to circuit Q30. Circuit Q30 connects from the drivers door switch t( the right front down relay. The feed is passed through the normally CLOSED contacts in the relay to circuit Q26. Circuit Q26 connects to the passenger switch. The motor current then runs through the switch to circuit Q22 which connects to the motor. The ground returns through circuit Q12 through the passengers switch contacts to circuit Q16. Circuit Q16 connects to the master switch then to the Z1 ground circuit.

For window UP operation the circuits are reversed. Circuit Q16 is the feed and circuits Q26 and Q30 are the ground.

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 F21 circuit through the switch to the Q22 circuit.

Ground for the motor is supplied on the Q12 circuit through the switch and back to the master switch on circuit Q16. A bus ban internal to the switch, connects the Q16 circuit to the Z1 circuit. The Z1 circuit is terminated at the instrument panel left side cowl.

For window UP operation, the circuits are reversed. Circuit Q12 is the power and circuits Q22 and Q26 are the ground.
