Normal Operation
With the ignition switch in the START or RUN position, the wiper/washer switch receives voltage from central junction box (CJB) through circuit 15-KA19 (GN/OG). When low speed or intermittent operation is selected, the windshield wiper motor receives voltage through circuit 32-KA10 (WH/GN). When high speed operation is selected, the windshield wiper motor receives voltage through circuit 32-KA11 (WH/BK). The windshield wiper motor is grounded through circuit 31-KA9 (BK).
Possible Causes
- fuse
- circuit 15-KA19 (GN/OG) open
- circuit 31-KA9 (BK) open
- circuit 32-KA10 (WH/GN) open
- circuit 32-KA11 (WH/BK) open
- CJB
- wiper/washer switch
- windshield wiper motor
