Sounds to me like your hvac control module is not functioning correctly if im not mistakin you have climate contolled zones

Only ran into this problem once, ended up that the HVAC controller needed flashed. Most shops will not be able to preform repairs of this nature, so your dealership is the best choice. Chrysler uses special programing that is separate from the OBD2 system for HVAC and security.
