As far as the water noise, there is a drain for the AC. It may be plugged. If you open the hood and look along the passenger side of the firewall, you should see a black rubber hose that is pointing toward the ground. Check to make sure it isn't plugged.

Now for the air stopping issue, you must have a vent door closing off the air flow. I realize this is most likely an S-10 blazer, but need to know for sure. They actually made full size blazers with this engine.

I have attached a schematic of the vacuum system for the HVAC system. Start by checking to make sure the supply from the engine is good.
