Re: 1996 dodge caravan heat problems
Unless chrysler decided to move it, the blend door and vacuum motor (likely what's bad) is up high on the center of the heater box. If you can see it you are lucky, if you can touch it, even luckier! Every one I've ever worked on was like this and required taking apart nearly entire dash to get to (and they wonder why these guys are all going out of business) Unless you have lots of time and patience, it's a shop job... Sorry....

Assuming the radiator is full of coolant, and the engine is reaching normal temp of 190 degrees, you could have a blocked heater core or the temp control valve may not be working on the heater hose. I would check to see if both heater hoses are getting hot.
Please see my tip at http://www.fixya.com/cars/r6235876-no_heat_fan_blowing_cold_air . These are genericinstructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.
Your blend door actuator is on front of the heater box by the core. Check to see if it is actuating when you change the temp setting. Take it off to see if you can open/close the door by hand. Let me know what you discover for additional help.
it sounds like a vaccume leak check under hood for vaccume line that goes through the firewall trace this line and look for leaks next pull controll unit out of dash most times this unit is worn an will leak causing lak of controll of the heat an airconditioning
Sounds as if the engine is not building up temp due to cooling system working. If engine temp gage is reading low try covering 1/3 of radiator with a piece of cardboard "Bumper side" to reduce the cooling effect.. just watch temp and out side temps if warming up outside or heavy driving remove the blocking to allow full cooling
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.
