How do you test Acura MDX rear wiper motor?

To test the Acura MDX rear wiper motor, first, ensure that the vehicle is turned off and the wiper switch is in the "off" position. Disconnect the motor's electrical connector and use a multimeter to check for voltage at the connector while activating the rear wiper switch; you should see voltage if the switch and wiring are functioning correctly. If there is voltage present but the motor does not operate, the motor may be faulty and should be replaced. If there is no voltage, further investigation into the wiper switch or associated wiring is needed.
