My ac hasn't worked all summer. I recently used freon and now I have cold air coming through my rear ac vents but it still comes out warm through the front vents. I've done some research and haven't found anything similar to my situation. I replaced my heater core over the winter and was also wondering if it was possible that I pinched a hose or something when I put everything back togther. thanks guys.

 

It might be the front expansion valve. It's on the firewall and mounts to the evaporator where it sticks though.
