d. Checking Cut-Out Switch—Cadillac Only
1. With ignition switch off, connect one end of a
#12 gauge jumper wire to by-pass feed ter-
minal
(over-ride) (orange-black stripe) and
the other end to the center terminal (master
control switch feed - red-white stripe).
2. Operate master control switch. If windows
operate with jumper wire but not with the cut-
out switch, the by-pass side of the switch is
defective.
3. With the ignition switch on, connect one end of
a #12 gauge jumper wire to center terminal
(master
c o n t r o l
switch feed - red-white
stripe) and the other end in the right and left
rear quarter or door and right front door feed
terminal (pink-black stripe).
i. Checking Feed Circuit Continuity
at Window Control Switch
1. Connect one test light lead to feed terminal of
switch block and ground other tester lead to
body metal (see Fig. 16-35).
2. If tester does not light, there is an open or
short circuit between switch and power source.
f. Checking Window Control Switch
1. Insert one end of a #12 gauge jumper wire to
the switch feed terminal and the other end to
one of the motor lead terminals in the switch
block.
Repeat this check on the remaining
motor lead terminal (see Fig. 16-36).
4. Operate control switches. If any of the win-
dows operate with the jumpber but not with the
cut-out switch, the switch is defective.
2. If the window operates with the jumper wire,
but does not operate with the switch, the switch
is defective.
