Power Window Switch: Description and Operation
CIRCUIT OPERATION
Master Window Switch (Left Window Operation)
When the window switch is moved to the window DOWN position, voltage is supplied on the F21 circuit through the CLOSED contacts in the
switch to the Q21 circuit. The Q21 circuit connects from the switch to the left front window motor. Grounding is provided on circuit Q11 from the
motor back to the switch. The ground is passed through the switch to the Z8 circuit. The Z8 circuit goes to its grounding point.
When window UP operation is selected, the power and ground circuits are reversed. Circuit Q11 is the feed and circuit Q21 is the ground.
Master Window Switch (Right Window Operation)
When the window switch is moved to the window DOWN position, voltage is supplied on the F21 circuit through the CLOSED contacts in the
switch to the Q26 circuit. The Q26 circuit connects from the master switch to the right window switch. A BUS bar internal to the right switch
passes the voltage through the switch to circuit Q22. Circuit Q22 connects from the switch to the right window motor. Grounding is provided on
circuit Q12 from the motor back to the right switch.
The ground is passed through the switch on a BUS bar to circuit Q16. Circuit Q16 then goes to the master switch. The ground is passed through
the switch to the Z8 circuit. The Z8 circuit attaches to its grounding point.
When window UP operation is selected, the power and ground circuits are reversed. Circuits Q12 and Q16 are the feeds and circuits Q22 and Q26
are the grounds.
Right Window Switch Operation
When the window switch is moved to the window DOWN position, voltage is supplied on the F21 circuit through the CLOSED contacts in the
switch to the Q22 circuit. The Q22 circuit connects from the switch to the right front window motor. Grounding is provided on circuit Q12 from
the motor back to the switch. The ground is passed through the switch to the Q16 circuit. The Q16 circuit connects from the right switch to the
master switch. Ground is passed through the master switch to the Z8 circuit. The Z8 circuit goes to its grounding point.
When window UP operation is selected, the power and ground circuits are reversed. Circuit Q12 is the feed and circuit Q22 is the ground.
