In this article, you will find information about the fuses of the Ford Low Cab Forward (models 2006, 2007, 2008, and 2009), including diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Ford Low Cab Forward
If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components.
Caution!
- Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.
- Always disconnect the battery before servicing high current fuses.
- Always re-install the protective cover to avoid water or fluids from damaging the PDB or other electrical components.
- Remove and install the cover carefully so that no wires or cables become disconnected or damaged.
Location of Fuse Boxes
Power Distribution Box (PDB):
The PDB is located behind the cab on the right-hand frame rail, behind a protective cover. To access the PDB, the protective cover must be taken off the vehicle by removing the two screws (shown in illustration), then gently pulling the cover off.
Once the cover has been removed, simply lift the tab on the PDB cover to access the fuses and relays.
Relays:
The relay box is located under the center of the instrument panel.
The instrument panel lower trim panel must be removed to access the relays. Remove the plastic rivet from the driver side of the trim panel.
Remove the two screws on the passenger side bottom of the panel, then the plastic rivets on the top end. Push the panel up slightly to disengage the locking tabs, then pull the panel toward you and off.
Reinstall the panel in the reverse order of the removal procedure.
