Wiper Inoperative

Check wiring harness, wiper ground strap and dash switch for proper connections and mounting. Check fuse. With ignition switch on, check for 12 volts at harness terminal which connects to No. 2 terminal. To by-pass switch, disconnect wiring at motor and connect jumper wire from No. 1 and 3 terminals to ground and a 12 volt source to No. 2 terminal. If wiper does not operate, disconnect transmissions from crank arm. If wiper still does not operate, remove from car and test unit. See 2-Speed Wiper (Off Car).
