h. Checking Wires Between Quarter Window
Switch and Quarter Window Motor
1. Disengage the in-line connector located in-
board of the quarter inner panel as required.
2. Insert one end of a #12 gauge jumper wire in
the switch feed terminal and the other end in
one of the motor lead terminals of the switch
block (see Fig. 16-37).
3. With a test light, check for current at the cor-
responding terminal at the in-line motor con-
nector. If tester does not light, there is an
open or short circuit between control switch
and motor connector.
4. Check other terminal.
. Checking Window Motor
1. Check window regulator and channels for pos-
sible mechanical bind of window.
2. Check attachment of
an effective ground.

repaired or replaced as required. Check the
other motor lead in the same manner.
j. Trouble Shooting of Power Windows
The following typical failures and corrections have
been listed as an aid for eliminating electrical
failures in the power window electrical circuit. It
should be noted that multiple failures in the circuit
may lead to a combination of conditions, each of
which must be checked separately.
