Chrysler 200, A/c not working

Hey , can someone please help me figure this out. I have a 2012 Chrysler 200 that I am having trouble with the a/c. It hasn't worked in a while but since summer is approaching i want attempt to fix it. I have started off by purchasing a can of Freon and trying to recharge the system. It worked great for about 2days. But at the same time when i turned off my vehicle i can hear a noise near the a/c hissing for about 30 seconds then shuts off. Trying to find the noise, i remove my front bumper & the noise seem to be coming from this part of my vehicle. Its an aluminum a/c tube near the bottom of the passenger side. I also noticed that one side of the tube is really cold and the other part is hot. The line is going into the bottom of the condenser. Is this normal??? I also pour a/c die to check for leaks and noticed that my condenser had bubbles on the bolt portion of the condenser.

Can someone tell me if i need a new condenser and why is the line cold and then hot. Could it be a blockage? How do i unblock it
