Chrysler Repair: Town and Country A/C, blower motor resistor, throttle position sensor

Question
I have an 02 Town and Country.  The fan that controls my air has started only working on high.  What does that sound like the problem could be, and should be relatively simple to fix??  I have just invested a ton of money in various repairs for this van and am really not looking forward to fixing yet another thing.  The last thing we had replaced was a Throttle Position Sensor.  Do you know if that has become a common problem with Town and Country's becuase it took about a month to finally get someone to diagnose that problem, but found several other things along the way that had to be repaired also.

Answer
U need a blower motor resistor

Open the glove box.
Flex both sides of the glove box bin inward near the top far enough for the rubber glove box stop bumpers to clear the sides of the glove box opening, then roll the glove box downward.
Reach through the glove box opening to access and disconnect the instrument panel wire harness connector for the blower motor resistor from the resistor connector receptacle (Blower Motor Resistor).
Reach through the glove box opening to access and disconnect the blower motor pigtail wire connector from the resistor connector receptacle.
Remove the two screws that secure the blower motor resistor to the evaporator housing.
