Dodge Caravan AC Heater Control only works on high mode?

This problem is very much noticed and seen on many other car models too.
The most common cause is that an electrical device called the blower motor resistor block, has failed. This device provides all the slower speeds. It is generally mounted in the HVAC [Heating, Ventilation & Air Conditioning] box, very close to the blower motor. FYI, we mechanics call the fan motor inside the cabin the blower motor. The electric fan motor behind the radiator is called the cooling fan motor.
If the resistor block is OK, then you have either a bad fan speed switch or a melted electrical connector at that switch. 95% of the time, the resister block is the problem.

This basic details will help.Thanks.
