Replacing fuses
In the event of an overload in any circuit, the corresponding fuse will burn and can normally be replaced with another one of the same capacity.
A blown fuse is recognized by having a broken filament.
Thermal current circuit breakers
These protection elements interrupt electrical circuits when they are heated due to an overload. Power will be restored as soon as the circuit breaker cools. In cases of frequent power cuts in a circuit protected by a circuit breaker, a Ford Dealer must be contacted, who must detect and repair the fault.
Thermal circuit breakers are installed in the following electrical circuits:
- Installation of the windshield wiper and washer.
- Cigarette lighter and horn.
- Electric drive of the windows and electric door lock.
- Installing the rear glass wiper and washer.
- Front main headlights.
The thermal circuit breaker for the windshield wiper circuit has a capacity of 4.5 Amperes, and is located behind the glove box.
The headlight thermal circuit breaker is integrated into the light switch.
Passenger compartment
The fuses for the vehicle’s various electrical circuits are located in the fuse box, located under the instrument panel, on the left side of the steering column. The fuse box can be opened by pressing down on the side latches located to the right and left of the box.
