Windshield Wiper Switch Test Refer to the following illustration and Turn Signal and Windshield Wiper Switch Test to resolve concerns with the urn signal and windshield wiper switch and wiper and washer switch circuits. "esting should be done with an ohmmeter such as Rotunda Digital Volt Ohmmeter 007-00001 or equivalent. NOTE: Terminals 1, 2 and 3 are the only ones used for 1is test.
