Park Switch Test

  1. With all previous jumpers disconnected, connect jumpers between F2 and A, between F1 and ground and between P and battery positive terminal. Connect voltmeter between A and ground. Wiper should run to park position and stop.
  2. If motor does not run but did in Motor Run Test, park switch is open. Clean switch contacts and retest. When wiper arm reaches park position voltage should be zero.
  3. If voltage remains at A with wipers parked, remove wiper arms and blades. If voltage drops to zero, arms and blades were improperly installed. If voltage still remains, switch contacts or gear and latch assembly are defective.
