Wiper/Washer Switch Circuit

  1. Disconnect 18-pin combination (wiper/washer) switch connector. Turn ignition switch to ON position. Measure voltage between terminal No. 17 (Blue wire) and ground. See WIRING DIAGRAMS . If battery voltage is present, go to next step. If battery voltage is not present, check wire harness, connectors and 25-amp WIPER fuse located in instrument panel junction block, behind left side of instrument panel. Repair or replace as necessary. Retest system operation.
  2. Turn ignition switch to OFF position. Check continuity between terminal No. 2 (White/Black wire) and ground. If continuity exists, check wiper/washer switch. See WIPER/WASHER SWITCH  under COMPONENT TESTS. Replace combination (wiper/washer) switch as necessary. Retest system operation. If continuity does not exist, repair open in White/Black wire between combination (wiper/washer) switch and ground connection. Retest system operation.
