20A circuit breaker gets too hot to touch

Asked by Aug 09, 2016 at 10:57 PM about the 1996 Ford Bronco Eddie Bauer 4WD

Question type: Maintenance & Repair

i am restoring a 1996 bronco. the 20A metal breaker according to the
diagram controls the 4x4, electric locks, tailgate window thru the key,
lumbar support and possibly a few others.  upon inspection of my fuse box i
just about burned my hand on this circuit breaker.  it was working (at least
the e-locks and tailgate window up to the point where i noticed the wires in
the harness' were corroded.  i have no idea if these wires that i tried to fix
control the above items.  
there are two sets of wires  4 strand/3 strand that is located behind the
drivers seat under the seat belt plastic cover. some of the colors are black,
black w/ blue strip, dark green and two green w/ yellow strip   when putting
the connections together several of the wires from each connectors were
corroded and pull out of the harness. i attempted to fix this problem by
cutting off all the wires (not at the same time) from the harness and
replacing them w/ quick connects and shrink wrapped the connections.  this
was the only adjustment/repair i had done to this truck and up to this time
all the electrical was working that i can remember.. today i doubled check
the connections to make sure i didn't cross up the wiring.  All wires match
up. the only thing i noticed that there was 2 sets of green wires w/ yellow
strips. its possible i crossed these but dont believe so since it appears each
of these wires were part of the separate wire harness...  any possible
suggestions on what the problem could be or a way to trouble shoot.. to
add insult to injury i know nothing of trouble shooting electrical in cars and
dont own any testing tools.    am i just better off taking to the dealership.

You really need some tools for this type of problem, I would forgo the dealership unless your loaded with cash, I suggest a good independant shop, this rig is old enough that most every shop will be able to locate and repair the problems you have, now I'm not saying it's going to be cheap, cause it sounds like you have a lot going on, but it will be cheaper than a dealership.
