The 3.3L V6 has a propensity to develop head gasket leaks, especially on the front bank of cylinders. The head gasket leak is generally on the flywheel end of the engine - right-side while viewing from the front of the engine bay.
I had this problem on my '94 Grand Caravan ES, and we had no heat! As soon as I tore it down and replaced the head gasket (actually I replaced both), we once again had normal heater operation.

Really? I participate on a number of minivan related boards (and am even a moderator on one), and for the Gen 3 and later vans (i.e. 1996 and later), I've never even once heard of folks having head gasket issues (errr, unless someone seriously overheated the engine).
FWIW, my former 1998 had a slow loss of coolant that was engine up in the engine oil (not a good thing), and all of the sages opined that the problem was a head gasket leak. One week during the summer of 2007 I pulled the heads off and replaced the gaskets, and guess what, not only did I not find any place where the head gaskets had been compromised, but the leak continued at the same pace as before. The problem turned out to be a ten cent "O" ring in the timing chain cover (a problem that is occasionally reported).

I also have not heard of head gasket leaks in these engines, especially not "a propensity for" them. While I do not think it is the most probable cause, a head gasket leak can lead to air pockets in the coolant channels and cause overheating, loss of flow to the heater core, etc. It is always worth exploring this option as it is certainly possible for the gasket(s) to fail, especially if the fluid level does not appear low and there was no recent service activity that could have introduced air to the system.
