Ok if your saying its a leak I will keep an eye on it not to overheat but It only happened once after a coolant flush. I really don't want to replace the heater core lol my next project coming up is rear disk brakes/aussie lockers before winter two birds one stone. Going to the junkyard Friday to pull Grand Cherokee backing plates.

Again, no way around it: If there is coolant coming out of your ac condensation drip hose, YOU HAVE A LEAK! A leak in your heater core. That is THE ONLY way that coolant could/would be in your heater box and dripping from that line. Might be a tiny little pinhole, but a hole nonetheless. Coolant cant magically appear in the heater box and drop out of that line.

And after reading your initial post again, if you have air trapped in your coolant and it hasnt been PROPERLY filled and burped, youre going to burn up your head gasket REAL FAST!

I burped the line properly got all the air out like I said heat works a little better. Think it's known as luke warm. I am going to reverse flush the heater core if water comes out there then I have a leak right? Also to answer it was coolant but it looked a little brown if it has been stuck for a while so I think I knocked something loose but it's not spilling anything out the hose now.

There is nothing to knock loose in there. No two ways around it: Thats the ac condensation drip line. The ONLY thing that should be dripping out of that hose is condensation from running your AC. If youve got coolant for sure coming out of there, your heater core is leaking. Sucks, I know, but there is nothing else going on that could/would cause coolant to come out of that line.
