Motor Runs Slowly at All Speeds

1. Disconnect wiring harness connector at motor.
2. Remove wiper arms and blades.
3. Connect an ohmmeter between battery positive terminal and terminal 3 on motor.
4. If motor runs and average ammeter reading is more than 6 amps, proceed to step 6.
5. If motor runs and average ammeter reading is less than 6 amps, proceed to step 9.
6. Check wiper linkage or pivots for binding. Disconnect drive link from motor.
7. If motor now runs and draws less than 3 amps, repair linkage system.
8. If motor continues to draw more than 3 amps, replace motor assembly.
9. Check motor wiring harness for shorting between high and low speed wires as follows:
a. Connect a voltmeter or test lamp to motor ground strap.
b. Set wiper switch on Low position.
c. Connect other lead to terminal 4 of wiring harness.
d. If voltage is present, there is a short in the wiring or wiper switch. If no voltage is present, proceed to step e.
e. Set switch to high position.
f. Move voltmeter lead from terminal 4 to terminal 3.
g. If voltage is present, there is a short in the wiring or wiper switch.
