Replace your fan resistor module located behind glove box. Same happened to me. Eventually the fan won't work at all. After some months, my blower motor stopped. I just replaced it today. I have an extra resistor. I'll sell it to you for $12.00 if you want. It's brand new. I bought a second one because mine stopped again. I was hoping it was the resistor again, but it turned out to be the blower motor. Bought at Auto Zone for $103.00. If you buy your own resistor, you should be able to buy $15 to $25. DO NOT get at a Chrysler dealer!! They will rape you on the part and labor.
