2011 Charger RT, 5.7 Hemi, Automatic transmission with 110,000 miles. The air conditioning is intermittent. One day it works, one day it doesn't do anything but blow hot air. It has been to our local Dodge dealer 3 times and our local mechanic twice, but no fix. They will replace a component or a fuse or play with the refrigerant level and say it is working when we pick it up and the next day it fails to work. No one has found a leak or indicated that the compressor or the clutch are not working. Has anyone else experienced this problem and what was the eventual solution to repair the system? Thanks.
