At first i had a leak coming from the tube connected to the heater core...so i switched out the tube and it seems to not leak anymore but now coolant is leaking from inside my car...its come to the point where it leaked to my back seats...so my guess now is my heater core has gone bad. before i switched out the tube it was blowing heat now after replacing the tube it just blows cool air...i thought it was the thermostat but the temp on my cluster seems fine...so what do you people think?

 

wow people on here are very helpful...by far the worst and unhelpful site ive been on...

 

Your heater core is done...you need a new one. If you expect everyone to hand feed you info then you're better off somewhere else. I'll bet you that you haven't searched one bit on this topic cause if you did you'd find that there are multiple threads on this topic on multiple forums. Go cry somewhere else n00b.
