Have Ford Questions? Ask a Mechanic for Answers ASAP
hello . is this a 5 amp fuse you are referring to ?
is this the fuse box you are referring to ? inside the vehicle or out under the hood ?
does that illustration look acurate ?
that is supposed to be a 5 amp fuse
this lists all the items that are protected by that fuse .
one minute please .
have you tried to disconnect the brake pressure switch ?
no that is only the electric brake light switch . the pressure switch is usually on the master cylinder or the brake line near the master cylinder .
try also unplugging the ABS Control module on the firewall
how/when did this start ? any other work done recently on the truck ?
refer to # 6 in the illustration for the ABS module
does your truck have an adjustable brake pedal ?
okay so we have a 1998 Ford F150 XLT 4X4 ? correct ?
refer to the description , it is in the dash inside the vehicle
the fuse that is blowing is protecting the ABS control module . The easiest way to fault it as the problem/cause or rule it out is to disconnect it . Did you have the vehicle scanned to check for DTC's related to the ABS system ?
you say the shifter is locked in park ?
did you reconnect the brake switch at the brake pedal ?
fuse #6 is for the shift lock actuator . have you checked it ?
the wiring diagram and fuse diagrams do not indicate that that should occur . Have you tried removing all your brake light bulbs and do you ahve a trailer plug ?
you do not need to accept the answer . * have a trailer plug ?
