I have a 2001 t&c limited with duel climate control and digital display. last month the blower motor would stay on high and only high and when you turn the power off to the controls by the on/off button the blower motor went into a higher speed. now the blower motor wont work at all. but the rear works fine.

any ideas on what it could be?

 

The blower motor running only on high speed was probably a result of a burned out blower motor resistor. As to why it's not working at all now, that's another problem. A Chrysler dealer can hook up his scan tool to the car and read trouble codes generated by the body computer that might give a clue as to what's wrong.
It's going to cost some $ but winter is coming and you gotta have heat.
