CIRCUIT OPERATION
When the operator selects window DOWN operation power is supplied on the F21 circuit through the switch to circuit Q21. Circuit Q21 connects from the switch to the power window motor. Ground for the motor is supplied on the Q11 circuit back to the switch. A bus bar, internal to the switch, connects the Q11 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 Q11 is the feed, and circuit Q21 is the ground.
