pretty sure! i know it is! heat works fine and so does the a/c! i did have a problem with the coolant bottle staying full and not going back into the radiator but it turned out to be the return line was clogged up so i fixed that! i know it's weird!

I've heard this could be caused by a blocked A/C drain...haven't had this myself tho.
