1993 Cadillac Deville Windshield Wipers

Not normal for either an '83 or '93, if you clarify which one you have, I will look up the test proceedure for you.

Test 5, Wipers Do Not Turn Off Unplug 6-pin wiper motor connector. Turn ignition on. Set wiper switch to OFF position. Measure voltage at connector terminal "B" (Gray wire). See Fig. 2 . If voltage is zero volts, go to next step. If voltage exists, check for short to voltage on Gray wire. If wire is okay, replace wiper switch. 1. Unplug 3-pin wiper motor connector. Measure voltage at 3-pin connector terminal "A" (Purple wire). If voltage is zero volts, repair short to voltage in Yellow wire between 3-pin and 6-pin connectors. If voltage exists, check for short to voltage on Purple wire between 3-pin connector and switch. If wire is okay, replace wiper/washer switch. 2.
