Test P

PINPOINT TEST P: THE HIGH/LOW WIPER SPEEDS DO NOT OPERATE CORRECTLY (INTERMITTENT WIPER MODE OK)

Test P1-P2:

Test P3:

Normal Operation
The windshield wiper motor receives inputs from the multifunction switch circuits 31S-XL50 (BK/OG), 31S-XL51 (BK/GN), 31S-XL52 (BK/RD), and 31S-XL53 (BK/WH). The wiper motor module (internal) will then control the wiper run/park relay (internal) using internal circuitry to control the wiper motor in conjunction with the wiper HI/LO relay (internal).

Possible Causes
- multifunction switch
- windshield wiper motor
