Test 31B - Wiper Motor Does Not Shut Off

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For wiring diagrams, see WIRING DIAGRAMS  . Perform TEST VER-1 after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting any module connector.
  1. Remove high/low wiper relay (relay No. 10) from Power Distribution Center (PDC). PDC is located on left front fender apron. See Figure . If wiper motor stops operating, go to step 3). If wiper motor does not stop operating, go to next step.
  2. Using DRB in voltmeter mode, check voltage on high/low wiper relay connector terminal "D" (Red/Yellow wire). If voltage is more than 10 volts, repair short to battery voltage in Red/Yellow wire. If voltage is less than 10 volts, repair short to battery voltage in Brown/White wire.
  3. Remove on/off wiper relay (relay No. 6). Using an external ohmmeter, check resistance between on/off wiper relay terminals "B" and "D". If resistance is less than 5 ohms, replace on/off wiper relay. If resistance is more than 5 ohms, go to next step.
  4. Turn ignitions switch to OFF position. Disconnect Body Control Module (BCM) Bone connector. Using DRB in ohmmeter mode, check resistance of BCM Bone connector terminal No. 1 (Dark Green/Yellow wire). If resistance is less than 5 ohms, repair open Dark Green/Yellow wire. If resistance is more than 5 ohms, go to next step.
  5. Turn ignition switch to ON position. Ensure wiper switch is in OFF position. Using DRB in voltmeter mode, check voltage on BCM Bone connector terminal No. 16 (Dark Green/Red wire). If voltage is less than 10 volts, replace BCM. If voltage is more than 10 volts, go to next step.
  6. Disconnect multifunction switch connector. Connector is located on upper part of steering column, behind trim cover. Using DRB in voltmeter mode, check voltage on BCM bone connector terminal No. 16 (Dark Green/Red wire). If voltage is less than 10 volts, replace multifunction switch. If voltage is more than 10 volts, repair short to battery voltage in Dark Green/Red wire.
