now what?? no low and mid again

I replaced my blower motor resistor maybe 2-3 weeks ago, after taking a 80 mile round trip, most of the time with my blower on, 5 mile left on the way back it just worked on high again, nother thing I noticed was that the controls for the HVAC was dang hot I checked the wires to see if there's something obviously wrong there, didnt find any, is this normal to go through them that quick?? that was a new one from the dealer too! :mad: :damnit:
