heating and cooling fans are generally one and the same. changing freon doesn't always fix the problem... did you have the system pressure checked for leaks first.
Second determine if the vents are opening properly (switching from heat to cooling) basically when you change to cool it closes air access to the heater core.

i had the same problem, i dont remember the name of the piece but its mounted right in between the driver side headlight and the radiator. its a relay that turns the fans on when the car gets hot. its mounted on the body of the car. there should be wires leading from the radiator to the piece im talking about.... good luck I also paid about 35 dollars for the piece

First of all make sure your anti-freeze is at specification level's as well as make sure With the engine cold start the vehicle remove the radiator cap and make sure you see the flow of anti-freeze while keeping your hands as well as your clothing away from moving parts feel both hoses going into your heater core if the one on top of hot one on the bottom is cold then you have a Clogged heater core in which case you will need to flush the system . a simple garden hose will do the trick simply remove Both hoses to the heater core with the hose at the bottom line apply the garden hose until liquid comes out at the top of the other hose will probably see a lot of gunk. Also ensure that the vacuum line to the round ball under the hood is connected and not dry rotted.this will cause a vacuum leak to not allow the switch to fully engage from cold to hot. I hope this helps you.

Have you checked the coolant level? What you describe is exactly what happens if the coolant level is low. When stopped at idle, hot coolant is not circulating through the heater core, so no heat. As the engine increases in rpm's when you pull away from the light, the water pump is spinning quicker, and some coolant is making it to the heater core. So check the level, and if it is low, keep an eye on it to see if it drops again. That of course indicates a leak somewhere. Get it fixed, as overheating the engine leads to costly repairs and worse case a new engine. Let me know how you make out with this.

Caravans are notorious for having bad fan control modules. It is a little electronic box mounted on the inside frame rail on the driver's side just behind the radiator. You have to look from underneath. It can't be seen from the top.
