Help Please!!

Problem is with my 96 GMC, leat I think it is a problem. I am noticing an extra ordinary amount of fluid coming out of the drain tap for the heater/AC. It doesn't appear to have any antifreeze in it, just the normsal very cold clear water.

What is bothering me in the last few weeks I lost about a quart or so of coolant. In two years I lost less than that. I don't see coolant in the oil and no leaky hoses or the radiator.

It just seems to be the AC drip part. Could the Heater core be leaking, but not drip out antifreeze/coolant?

Am I worring over nothing.?

I don't have a pressuse tester to test the system, and it is not running hot.

Any ideas.

I'd hate to be doing the 50 mile trip to and from school after work Monday or Tuesday and have it crap out on me.

Thanks folks.
