Ok, my car does the exact same thing and the last post (about air in the coolant) makes a lot of sense. My car ONLY does this at startup (though, not on a "hot" startup / restart).

* My a/c condensation DOES drip out correctly.

So, do I just top it off and let it run, do I do this with the cap or or off?

Also, weird situation here, my car's a/c works great -- all the time. HOWEVER, when I go up a very long, extended hill -- like 5 miles up a mountain -- the a/c stops blowing cold and then fogs up the windows.

What is this, and are these things related (gurgling in dash)?
