My 2002 TJ SE has 54,000 miles on it and the heating and AC controls no longer work . I can control the temp, but changing where the heat or AC comes out does not work. I had a similar issue with a 2006 TJ and wondered if anyone else had the same problem. Also, should I replace the heating/ac control module with a new Mopar unit or use a different manufacturer. Thanks in advance for your thoughts.
