Just like the title says. Last winter i had a new heater core put in my car, because I was getting a lot of green tinted condensation on my windshields inside my car. I THOUGHT it was fixed, cause it only seemed to do it when it was cold out, and by the time I put in the heater core it was getting warm out. Well, today I got in my car for lunch and the windshield, side windshield, arm rest was all covered in condensation, plus when i fired up my car, it wanted to die on me a couple times, I gave it a little gas to get it out of it... after it warmed up a little it seemed ok? I turned on the defrost to get rid of the junk. I dunno if it was my heater core after all now... I have a new one in there. And I dont know if the condensation and my car almost dying are even related or not... any thoughts? Might have to give in and take it to a mechanic for a good diagnostic. Thanks in advance!
