Wiper Will Not Shut Off

Determine whether wiper has both speeds, low speed only or high speed only, then operate wiper by by-passing switch as previously outlined. See Wiper Inoperative.  If wiper operates correctly and has both speeds, lead to switch from No. 1 terminal is grounded or switch is faulty. If wiper has low speed only, lead to switch from No. 3 terminal is grounded or switch is faulty. If wiper has high speed only, lead to switch from No. 3 terminal is open or switch is faulty. If wiper still does not operate, remove from car and test unit. See 2-Speed Wiper (Off Car).
