HVAC heater control panel issue / melted wires

Hey guys,

Did some research on the site before asking, but not sure any apply to my issue. I have a 99 with AC with an erratic ac control panel. Sometimes it works (all speeds), sometimes it doesnt. AC used to kick on and off in 4 second intervals but lately would not kick on at all..so i replaced the heater control switch with a used unit that worked in another 99 and it worked on speed three only and the ac wouldnt kick on.

Looked behind the unit and this is what i found:

Its burned on the second wire terminal....Whats the deal?...i saw some suggest a blower resistor, but only when speed 4 worked...was there an overload of some kind? why wont the ac kick on? what do i need to research next?
