Maybe your heater core is leaking. It's in the dash on the passenger side. It's in a case with the evaporator core for the a/c system. It's a pain but something you can fix yourself if you are up to a challenge.

haynes manual has some info on changing the heater core. If it is the heater core, you might as well change the evaporator core as well. I have had mine out a few times in recent weeks and it sure is a fun job to do.

My truck is a 95, your's may be a little different but the idea is the same.

Disconnect the battery - don't want to set off the airbag. Have a shop evac the a/c system, drain the coolant. Remove the lower dash on the drivers side, remove the instrument cluster face (may need to drop steering wheel - i didn't have to), remove the ash tray, remove the glovebox. These are all held in with screws - either phillips or torx.

disconnect the vac lines from the a/c system (here's a problem i ran into, one of my vac lines runs into the engine bay and connects to the engine vac system behind the intake and was a little hard to find/see). There's a pig tail connector on the back of the heat/ac controls, that will need to be disconnected as well as remove the lines from the actuators (one on lower drivers side and one on lower passengers side). You'll need to disconnect the hot/cold selector - can do it from the back of the heat/ac control unit. You'll need to move the antennae wire out of the way, disconnect power to the blower motor. Alot of wiring under there, be sure to keep it up out of the way.

Remove the nuts (4 on mine) holding the evaporator case to the firewall. Plug the a/c and heater cor lines so you don't leak stuff inside the cab.

Remove the evaporator case, take it apart and remove the heate core and/or A/C compressor and replace. Be sure it seals when you put it back together or wise air will be coming out the passenge floor board. You may have a couple screwes holding together the duct work. And you'll have to remove a couple pieces of it. Be sure to connect it back up right.

Do a search I think someone posted some good instructions on doing this with a later model.

Now you see why shops charge $500+ to do this.

Haynes has info on heater core - nothing really differnet for evaporator core. I have a subscription at alldatadiy.com which had some helpful information.

It's early in the morning, hope i didn't forget anything. Someone please correct me if i'm wrong.

forgot to mention you'll need to disconnect 2 hoses at the top of the case for the defroster - these are round and slide off.

just look around before you start yanking stuff out.

to get the case out,pull back so the screws come inside the cab then slide it over toward passenger side , tilt it down so the screws are facing down and pull it out the passenger side door.

Sounds like the heater core considering its warm
out you can get a tube and hook the core hoses
togather under the hood and run the truck until
you get it replaced

It happens they do blow out and leak usualy just
drip but it sounds like your burst to drop that
much coolant
