Blower Motor power wire getting very HOT

96 HR Endeavor, Freightliner chassis, power wire suppling 12 v. for selector switch (dash AC and heat and fan) got so hot it melted fuse box connection. replaced wire and fan several times (new) still same problem. direct wire 12 v feed lets fan run without heating wire.
When the selector switch is turned on the wires gets hot quick. (with 12v supplied to fan with seperate wire.)

Any ideas, didnt find any bare wire grounding out or loose connections, I think the switch could be bad so Ill order a new one to try.
