Replaced climate control unit and still will not work except on high. Checked breakers and blower fuse and they are working. Would this be the blower motor or temperature heater fan resister?

Re: Heater Control Switch Only Works on High
It appears there is a resistor block there, either at blower connection area, or at firewall area on passenger side under cowl somewhere. It is quite common for blower to only work on high when resistor goes. Look for block, or base, 1-1/2" x 3" approx. with electrical connector to it.

Assuming you have already checked all the fuses, you probably have a failed Body Control Computer, which manages operation of climate control, radio, lighting, alarms, and a host of other functions. Your Chrysler technician can confirm that. Be warned: a BCC can cost a LOT of money, as in many '90s Chrysler products, they had to be programmed at the factory for your specific vehicle; a junkyard unit will not work in any car but the one it came in.
Almost sounds like your climate control switch is bad as it controls everything including the switching and blower speed with the exception of the blower speed being a blower resistor issue (allows multiple speeds).
When the blower works only on the high setting its usually a bad blower resistor which is right near the blower motor. now you say it would always blow high regardless of the fan speed setting that would indicate probably the climate control unit or a connector problem somewhere. finally it not working at all may be the climate control unit or connection went bad even further. it might have a blown fuse or a bad blower motor in addition to the climate control unit or connector problem .check for power and ground at the blower motor. the power is supplied from fuses and may have a relay also. the ground is supplied from the climate control unit and goes through the resistor to control the fan speed. good luck
I replaced the fan module under the glovebox on my 2005 Town & Country last night. Mine would not shut off at all with key on. It only blew on high no matter where I set the switch. Mine also had the climate control which makes a difference. If it is not the auto climate control it is usually the blower resistor if the other fan speed selections don't blow at all except on high.
REMOVE HEATER BLOWER MOTOR HOT WIRE BLOWER MOTOR IT.IF IT WORKS.YOUR AC AND HEATER CONTROL SWITCH IS FAULTY.CHECK HVAC FUSES AND CHECK BLOWER MOTOR RELAY.IF BLOWER MOTOR DONT WORK WHEN HOT WIRE REPLACE IT.IF ALL CHECK OUT GOOD.HAVE DEALERSHIP DO A DIAGNOSTIC TEST ON YOUR CLIMATE CONTROL SYSTEM.
