Switch diagnosis in this group.
(1) Remove the door trim panel as described in
this group.
(2) Disconnect the power window motor connector.
Apply 12 volts across the motor terminals to check
its operation in one direction. Reverse the connec­
tions across the motor terminals to check the opera­
tion in the other direction. Remember, i f the window
is i n the full up or full down position, the motor will
not operate in that direction by design. I f OK, repair
the circuits from the motor to the switch as required.
If not OK, replace the faulty motor.
(3) If the motor operates in both directions, check the
window's operation through its complete up and down
travel. If not OK, refer to Group 23 - Body Components
to check the window glass, tracks, and regulator for
sticking, binding, or improper adjustment.
