Welcome, I'm Chris (aka Moose). Thanks for allowing me to help you for a much lower fee than a dealership.


Is this a truck or van?

Do you know the fuse number?

Does it blow immediate when the lights are turned on?

2003 f350 7.3 supercrew truck fuse 18. Blows immediately opon insertinting the fuse I don't get the fuse all the way in and it arks and blows the fuse
Expert:  Chris (aka- Moose) replied 7 months ago.

Fuse 18 goes the brake pedal switch and the indicator flasher relay in auxiliary relay box 1 behind the left side of the dash. This fuse powers the light green/red wire. Your looking at a most likely wire short here. I recommend starting by looking at the brake switch for chaffed grounded wiring.
