2007 chevy tahoe front ac works fine but rear is blowing hot. I have already checked freon and it is fine.

Aside for checking the system for fault codes, I would suspect a faulty blend door actuator, or faulty expansion device. You can try disconnecting the battery cables and touching them together for a minute or two. Reconnect and see if the behavior changes.
