I have a 300C which I bought new on 22 August which now has less than 1,000 miles. I went on a short trip in S. California during a hot spell. Twice on the way the A/C froze up and twice on the return the A/C froze up again. The A/C was on full auto with maximum cooling requested on both the driver and passenger. Slowly the A/C level declined until complete freezeup occured. Shutting off the air and opening the windows helped the unit to thaw. I took the car into a 5* dealer and they said they could not duplicate the problem. After coming home from the dealer I entered this GREAT website and found the TSB 24-012-05 for the exact same problem with the A/C. My complaint was why did the dealer not know about the TSB and use it to reprogram the HVAC Automatic Temperature Control (ATC) as stated in the TSB while I was in there. I called the Service Manager and he told me they did not have the CD version of the flash update and that he would call me when they did get it. I reread the TSB. The TSB clearly states that the dealer can get the flash from the Internet site for Chrysler StarScan flashes that they have access to. I have a call into him to find out why they can't update it via the Internet. I did call Chrysler Customer Service about this and complained. I am waiting for the Service Manager to call back. Has anyone else had this problem? Will advise what happens. Regards, Bob.
