Everything is working from the engine to the heater core. When I turn the fan on high, I get luke warm air. Could it be a stuck blender door?If so, I can I get to it?
My car had the same problem. On mine the heater core was partially clogged. I flushed it and a bunch of junk came out of it, now it heats really good, you could try that.
The stuck door could be the problem. I had that happen on a Dodge sedan I once owned. I don't remember how but I got into the system and discovered a door that was just flapping back and forth thus giving me alternating warm air or no warm air at all. It might have been that the cable had come off where it was fastened to the door.

a bad heater core will just leak. it could leak alot. do you ever smell antifreeze? check the coolant level. it can get pretty low before it will overheat. the thermostat should be ok but there could be corrosion. when you had the water pump replaced was the cooling system flushed? 2001, its probably due for a flush. what coolant does it take? (green or orange)

240cpa is right.dodge caravan does not have a heater control
valve and coolant constantly crculate in heater core . use the temperature contorol on instrument panel if you notice no change in heat your blend door in heater box is not moving . and as 240cpa mentioned make sure the t stat is not stuck open.

It's a big job. Drain the coolant down, recover the freon in the ac system and disconnect the lines and heater hoses. Lower the steering column, remove the instrument panel assembly, remove the heater housing. Split the case halves on the housing and there you are. Usually around 500 to 700 dollars at a dealership.

You may need to replace your thermostat. Also while you are at it flush and fill your cooling system.
