    I have the same trouble. I went out one day at -18 degrees and turned it on and nothing. Only the highest setting for the blower runs. All other speeds of the blower are dead.

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. It has 2 sets of wires coming off of it. A do it yourself fix.

Looking at the schematics , hi speed is on a seperate line , all other speeds go through the front blower motor resistor block , on HVAC assembly behind glove box . can't rule out a bad speed switch but odds are your resistor. if your handy with a volt/ohm meter your could check it first .

Sounds like you have a problem with the reostat. That is what gives your fan the lower speeds. High speed is on a different circuit. It is located somewhere on the heater box, pull it out and see if it looks burnt or rusted. If it is it should be replaced.

A/C on caravan only works on high


There is a front-rear blower motor relay control that is involved in the circuits. This control module could be the problem. The blowers bypass the resistors to run on high speed.
You may have to get a repair manual with detailed wiring diagrams to trace the circuits.
