How do you check a wiper motor on a g body?

To check a wiper motor on a G-body vehicle, first ensure the ignition is off and disconnect the battery. Next, remove the wiper motor from its mounting and inspect the wiring for any damage or corrosion. Use a multimeter to test for power at the motor's connector while operating the wiper switch; there should be voltage present. If there’s power and the motor doesn’t operate, it may need to be replaced.
