8S - 4 POWER WINDOW SYSTEMS
DIAGNOSIS AND TESTING (Continued)
NOTE: Because this switch contains active elec-
tronic elements for the Auto-down feature, this
switch function cannot be checked with a continuity
test. If the problem being diagnosed involves this
function, reconnect the switch to its wire harness
connector, connect the battery negative cable and
turn the ignition switch to the On position. Back
probe the wire harness connector cavity for switch
pin number 8 and check for the proper switch out-
put while actuating the switch. With the switch in
the Up position, there should be continuity to
ground at pin 8. With the switch in the Down posi-
tion, there should be battery voltage at pin 8.

firm proper switch operation. See Power Window
Switch in the Diagnosis and Testing section of this
group.
(1) Disconnect and isolate the battery negative
cable. Remove the trim panel from the door with the
inoperative power window.
(2) Unplug the power window motor wire harness
connector. Apply 12 volts across the motor terminals
to check its operation in one direction. Reverse the
connections across the motor terminals to check the
operation in the other direction. Remember, if the
window is in the full up or full down position, the

motor will not operate in that direction by design. If
OK, repair the circuits from the power window motor
to the power window switch as required. If not OK,
replace the faulty motor.
(3) If the motor operates in both directions, check
the operation of the window glass and lift mechanism
through its complete up and down travel. There
should be no binding or sticking of the window glass
or lift mechanism through the entire travel range. If
not OK, refer to Group 23 - Body to check the win-
dow glass, tracks, and regulator for sticking, binding,
or improper adjustment.
