Circuit Breakers


Pickup, Navajo and MPV models use circuit breakers for components which have a high start-up amperage pull (such as power windows). All breakers will automatically reset if they have been tripped. The circuit breakers are replaceable (should one go bad or not reset) and can be found on the fuse panel.

All circuit breakers on Navajo are located in the fuse panel except for a 4.5 amp circuit breaker for the rear wiper/washer and a 22 amp circuit breaker for the high beams which is integral with the headlight switch.


See Figure 1

The circuit breakers are replaced in the same manner as a fuse. Simply pull the breaker from the fuse panel to remove.
