CIRCUIT OPERATION
When the operator selects window DOWN operation power is supplied on the F21 circuit through the switch to circuit Q29. Circuit Q29 connects from the switch to the left power window down relay. The feed is passed through the normally CLOSED contacts in the relay to circuit Q21. Circuit Q21 connects from the relay to the motor. Ground for the motor is supplied on circuit Q11 back to the master switch to the Z1 ground circuit.

For window UP operation the circuits are reversed. Circuit Q11 is the feed and circuits Q21 and Q29 are the ground.
