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.

When rear wiper function is selected, the wiper/washer switch sends a voltage signal to the GEM through circuit 32-KA35 (WH/RD). The GEM provides a ground signal to the rear wiper relay coil through circuit 91S-KA29 (BK/YE). The relay energizes and provides voltage to the rear window wiper motor through circuit 32-KA28 (WH/RD). When the rear wiper switch is turned off, the rear window wiper motor continues to receive voltage through circuit 15-KA28 (GN/BU) until the wiper motor completes its cycle and the internal run/park switch opens the circuit.

Possible Causes
- circuit 15-KA9 (GN/RD) open
- circuit 15-KA28 (GN/BU) open
- circuit 32-KA9 (WH/BU) open
- circuit 32-KA9A (WH/BU) open or short to ground
- incorrect front wiper arm adjustment
- incorrect rear wiper arm adjustment
- windshield wiper relay
- windshield wiper motor
- rear window wiper motor
- central junction box (CJB)
