SOURCE: Wiring the replacement 3 speed switch (fan motor)
I called King of Fans and the rep that I spoke with gave me the correct wiring for the 3 speed switch:
L White
1 Yellow
2 Blue
3 Black
The problem is that after I wired it this way I am getting the same result (off on 3 settings and a motor hum on 1 setting). So, either the Westinghouse switch that I bought at Home Depot is not compatible or it is the capacitor. The saga continues.

Replacement should be simple. Just do a one for one hookup with the new part, after you unplug it first.

What I did was (but be VERY VERY carefull) is have the fan plugged in, and check which wires give which speed when you touch the main wire. VERY carefull. I'm not liable for any harm done to you or your fan.

Its the switch behind the fan nob thats not making contact, you have to pop the cover off the dash where the radio fan and other gizmos are. Then remove the fan nobs by pulling them straight off after that unscrew the housing unit inside is the switch. You must carefully pry this open so as not to break the plastic clips holding it together the switch thats fryed should just pop out easy replacement fan switch! If my mind serves me right it costs 40$ to replace if you order from chrysler.
