Can a low speed windshield wiper still work?

Use your multimeter to bridge between the low speed terminals on the switch and the wiper motor; with the switch moved to “Low” you should get at least a 10-volt reading. If you do, the wiring is fine; if you do not, the wiring has failed. Repeat the exercise with the intermediate speed.
