Fan motor fuse blowing

[Acuta73]

Put a multimeter on the body, cab and bed, and the chassis. See if you get a positive current anywhere, might have a low-voltage short/leak somewhere in the wiring. If so, first place to check is behind the heater controls if you have the kind that slide in that truck (dunno bout 2nd Gen too much).

Do the multimeter test with the engine off, then again with it on. Won't help you find the break if there is one, but will help you figure out if there is one to begin with.

Other possibility is a ground fault, which I am personally terrible at diagnosing.


Edit: Come to think on it, replacing that fan motor might do the trick by itself....bad motor can cause a V-leak
