Wipers Not Operating
NOTE:
Perform WINDSHIELD WIPER TEST 5A before proceeding with this test. For connector terminal identification and wiring diagrams, see
BODY CONTROL COMPUTER - INTRODUCTION article. Perform VERIFICATION TEST: VER-2A after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Disconnect motor connector. Do not disconnect jumper wire. Using scan tool in voltmeter mode, measure voltage at terminal "E" (Brown/White wire) on wiper HI/LO relay socket. If voltage is 10 volts or less, repair open Brown/White wire. If voltage is greater than 10 volts, go to next step.
- Ensure ignition, lights and accessories are off. Using scan tool in ohmmeter mode, measure resistance at "E" (Black wire) on wiper ON/OFF relay socket. If resistance is less than 5 ohms, replace wiper motor. If resistance is 5 ohms or greater, repair open Black wire.
