Motor And Linkage: Notes
- Place wiper switch in "LOW" position. If motor can be heard running, check output shaft. If shaft is not turning, replace gearbox. If shaft is turning, check wiper linkage.
- Connect a voltmeter to terminal "L" at motor with switch in "LOW". If voltage present and motor not running, connect jumper from "P2" to ground. If motor runs, switch or wiring is faulty. If not, check motor brushes and armature.
- If voltage is present intermittently, check for short circuits in motor, wiring, and switch. Disconnect wiring at motor and remove wiper arms. Connect an ammeter between battery and terminal "L", and a jumper between "P2" and ground. If motor runs and current draw is less than 6 amps, problem is in switch and wiring.

- If motor does not run or current draw is more than 6 amps, disconnect motor from linkage. If motor now runs and current draw is less than 3 amps, fix linkage. If motor does not run or draws more than 3 amps, repair or replace gearbox and motor.
