Test 33B - Wiper Motor On/Off Wiper Relay Control Circuit

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. Using DRB, read wiper park switch status. If DRB displays WIPER PK SW CLOSED, go to step 5). If DRB does not display WIPER PK SW CLOSED, go to next step.
  2. Disconnect multifunction switch connector. Connector is located on upper part of steering column, behind trim cover. If motor is not operating, replace multifunction switch. If motor is operating, go to next step.
  3. Remove on/off wiper relay (relay No. 6) from Power Distribution Center (PDC). PDC is located on left front fender apron. See Figure . Reconnect multifunction switch connector and place wiper switch in low speed position. Using DRB in voltmeter mode, check voltage on on/off wiper relay connector terminal "C" (Dark Green/Yellow wire). If voltage is more than 0.2 volt, replace on/off wiper relay. If voltage is less than 0.2 volt, go to next step.
  4. Disconnect Body Control Module (BCM) Bone connector. BCM is located behind right kick panel. Using DRB in ohmmeter mode, check resistance of on/off wiper relay connector terminal "C" (Dark Green/Yellow wire). If resistance is less than 5 ohms, repair short to ground in Dark Green/Yellow wire. If resistance is more than 5 ohms, replace BCM.
  5. Disconnect wiper motor connector. Connector is located on engine compartment firewall, just right of power brake booster. Using DRB, read wiper park switch status. If DRB does not display WIPER PK SW CLOSED, replace wiper motor. If DRB displays WIPER PK SW CLOSED, go to next step.
  6. Turn ignition switch to OFF position. Disconnect BCM Bone connector. Using DRB in ohmmeter mode, check resistance of BCM Bone connector terminal No. 2 (Tan/Red wire). If resistance is less than 5 ohms, repair short to ground in Tan/Red wire. If resistance is more than 5 ohms, replace BCM.
