Wiper Control Switch Test

Fig. 1 Windshield wiper switch continuity chart. 1982---87:

1. Remove wiper switch.
2. Operate switch in all positions and check continuity between switch terminals using a self-powered test lamp or ohmmeter. When testing switch in intermittent wipe position, variable resistor must be checked with an ohmmeter.
3. If switch continuity is not as specified, replace switch.
