A/C Fan speed switch melted
Hi all!
I have a 2005 Magnum SXT, although this problem seems to be more widespread. The blower fan switch had melted. I changed it, and it melted again. Well, just two of the prongs. I was at pull-a-part looking for the wiring harness that plugs into the switch; and i found that there were quite a few of those that melted. Even the newer style a/c switch connectors had two of the prongs that had signs of overheating and melting.
What could be causing this and how do I fix it? I mean, with it being this widespread, surely someone knows something about this epidemic.

I'm not a scientist, but when I see 9 out of 10 vehicles with this plug and newer version of this plug with the same two terminals showing signs of overheating, I figure it's a common problem. And I wouldn't put a junk blower in it. I did finda few places online that focus on this problem. According to them, the motor is pulling too many amps. I should get to it and see if it spins freely or if it is stiff to spin. Of course, they may not be scientist either.
