    If its not coolant it could be tranny fluid or engine oil. They all flow through the radiator. What color is the fluid? It could also be windshield washer fluid, the bottle is up front on the driver side.

    yeah sounds like your HVAC drain is clogged.... Should be able to see it in the engine compartment.....

    Should be somewhere under the blower motor IIRC... Should just look like a short piece of hose..... Been a while since I've worked on that body style though....

    so i think i`ve fixed te problem.....under the windshield where the wiper trans where the intake for fresh air is, i unsealed the panel over it...and put water in around it and sure enough it filled the blower motor i bought rubberized sealer sprayed all around it and inside....seams where the intake goes through to the outside, it has a foam leaked like crazy with that done i resealed the access panel in on top of it and resprayed water to test far so fingers crossed thats the end of that.....

    The drain tube is located near where the heater hoses go through the firewall. Just a little pop-in rubber elbow.
