- Disconnect wiring connector at motor. Remove wiper arms. Connect ammeter between battery and motor terminal No. 3. See Figure . Ensure motor is properly grounded. If motor operates and average current flow is more than 6 amps, go to next step. If motor operates and average current flow is less than 6 amps, go to step 3).
- Check wiper linkage and pivots for binding. Disconnect drive link from motor. If motor now runs and draws less than 3 amps, repair linkage and pivots. Replace motor if it runs and still draws more than 3 amps.
- Check motor wiring harness for shorts between high and low speed circuits. Connect voltmeter or test light to motor ground strap. Set wiper switch to LOW position. Connect other lead of voltmeter or test light to terminal No. 4 of motor wiring harness. If voltage exists, a short exists in wiring or wiper switch. If voltage does not exist, go to next step.
- Set wiper switch to HIGH position and move voltmeter lead or test light from terminal No. 4 to terminal No. 3 of wiring harness. If voltage exists, a short exists in wiring or switch. Repair as necessary.
