Circuit Breaker
Circuit breaker is located in wiper control switch on all rotary switches and in fuse panel for slide wiper control switches. All pin terminal switches have a rating of 8.25 amperes and all blade terminal switches have a rating of 7.0 amperes. On models with the circuit breaker located in the fuse panel, the rating is 7.5 amperes. The following test does not apply to vehicles with circuit breaker located in the fuse panel. On models with circuit breaker on wiper switch proceed as follows:
- Before connecting tester leads as shown in illustration, short tester leads together and adjust current draw until it equals circuit breaker rating. Connect switch to tester and leave switch connected for ten minutes. Current reading should remain at rated current. If circuit breaker opens during the ten minutes, replace wiper switch assembly.
- Short tester leads together and adjust current draw until it is twice rated current. Connect switch to tester and current reading on ammeter should drop to zero within 30 seconds. If it takes longer than 30 seconds for breaker to open, replace wiper switch assembly.
