Sounds like resistor is faulty. I believe on that vehicle, look up under dash behind glove box, and you should see blower & the harness that runs from it to a resistor attached to housing/duct. Pull connector off to stop blower. Replace resistor.

01- Dodge Caravan AC Heater Control it only works on high none of the speeds work when I rotate the switch from low to high. Is this a swith problem or a motor problem?


Most likely neither. The most common cause is that an electrical device called the blower motor resister 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.

Fan control knob on a/c and heater will only run on high speed. 2003 dodge mini van


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.

Heater fan switch only works on high speed setting


Check the heater resistor block in the heater housing. It controls the other speeds.

2002 dodge grand caravan heater blower only works on high spped


If you are looking for the fan blower resistor, it is located behind the glove box. No tools need to get to it and a nut driver to remove the 2 screws to replace it. A 20$ part.

Heater fan regulation


2002 Grand Caravan. The rear heater also has a resistor for the fan speed control.(3 speed) It is located under the rear passenger side plastic cover. You can take off the rear tail gate lower plastic piece and this will let you pull out the side panel. You can reach in and take out the two screws that hold in the resistor and unhook the wiring adapter. You do not have to take off the whole side panel as you can reach in from the back. The resistor unit can be bought at you local dodge dealer.
