I waisted a lot of gas and time going back and forth trying to fix the leak in ac , It should have been fixed 100% the first time with a dealer and the die they put it to find leaks. They said it is all set and no leaks found .After going back the second time in less than 2 weeks it stopped blowing cold air, returned it to have them tell me it is leaking from a gasket. Then 1 week later returned again 3 leaks later .They sent it to an outside ac garage to fix.
