I have some experience with this. If your fan only works on "high" setting, you probably have a failed resistor module controling the heater/ac fan motor. This happens to alot of Chrysler products & is a documented issue. I recently replaced one in a 2000 Chrysler Town & Country. It is fairly easily replaced by accessing the area near the fan. You may have to remove the glovebox & underdash panels. Sometimes you can replace it from under the hood if it is mounted to the firewall near the fan motor. It is about 4" x 1" in size. The reason you have "high" speed only is because the resistors are used to limit the full speed. There are several resistors on the module, but only one fails & prevents the others from working. It is supposedely caused by a fan motor that is working harder than if it was new. So the problem may happen again in several months. But it's worth replacing the resistor module since it is about $20 retail. If it happens again, you may want to consider replacing the fan motor. I have not done your particular car, but I hope this helps. I would definetely tackle it myself. The dealer will charge you hundreds.

I've had this same problem, but on a GM car. All I did was replace the blower motor relay and it was fine. As long as you know where to look for the resistors and relays, its a 5 minute fix. I'd definitely try and do it yourself.
