Normal Operation
When low speed 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). When intermittent operation is selected, the generic electronic module (GEM) sends an intermittent ground signal to the windshield wiper relay through circuit 91S-KA12 (BK/WH). The relay energizes and sends voltage to the wiper/washer switch through circuit 32-KA19 (WH/BK). The wiper/washer switch sends voltage to the windshield wiper motor through circuit 32-KA10 (WH/GN). When the wiper/washer switch is turned to the off position, or between intermittent pulses, the internal run/park switch in the windshield wiper motor provides voltage to the windshield wiper relay through circuit 32-KA9 (WH/BU) until the wiper motor completes its cycle and opens the circuit.

Possible Causes
- circuit 32-KA10 (WH/GN) short to voltage
- circuit 32-KA11 (WH/BK) short to voltage
- circuit 32-KA19 (WH/BK) short to voltage
- circuit 91S-KA12 (BK/WH) short to ground
- wiper/washer switch
- windshield wiper motor
- windshield wiper relay
- central junction box (CJB)
- GEM
