Had intake manifold gasket replaced June 09 (at the dealer). Since then, I have had a huge puddle of water on my garage floor (5' long x 3' wide) it never goes away. Cold to luke warm air when climate control is set in the 70's. Have to punch it up to mid 80's to get heat. When I do that it sounds like a little door slams open and heat just pours in. It was suggested that it might have a clogged heater box hose. Any other ideas? Am I in for big $$$ repair bill? Thanks

I had the car in at the dealership on Tuesday of this week. He checked everything. All fluid levels were okay. He pressure checked the A/C unit. Could not find anything. So the plan is that I clean up the garage floor (which I have done) and wait and see if a puddle forms. I haven't had the car out on a run since cleaning up the floor. As far as the blender doors go, I had done some research before going to the dealer and found out that it involved removing the dash etc. - Very labor intensive. So I said forget that problem. If the heat finally totally stops, then I will try and see if they still make those little heaters that can be plugged into the cigarette lighter. I just don't want to put a whole lot of money in this eleven year old car.
Thanks for you reply.

First, you need to locate where the leak is coming from. After that, as far as the heat is concerned, if you hear a door close, it's the blend door that is sticking and causing the heat problem. The heater core isn't plugged.

Let me know what you find.

Let me know what you find. Also, the blend door is a pain, but it is doable.
