My A/C has worked perfectly well since I got the car in February 2018. I leave it on all the time Summer & Winter. Generally, I have it set on 24 degrees when I start in the morning and reduce it to between 18 & 21. Suddenly, it is behaving differently. Yesterday and this morning, I had to turn it up to Hi to get my normal morning heat and when I reduced it to 24, it started blowing cold air. This was with 6 degrees outside temperature. The only other strange thing that coincided with the A/C problem on the first day, was that on starting the car, the idle was uneven. It hasn't done this since and never before. I hope this all makes sense to someone, as the warranty ran out last month. Thanks
