The AC started blowing warm air instead of cold air especially on the drive side. After doing lot of research, I found out that 10th gen civics have AC problem. Since recharging was very expensive for RY1234, I tried to refill myself by purchasing small cans of coolant from ebay. AC worked okay for a month or so, and I had to buy another can. The same issue repeated in the summer of 2018 and yet again I bought the same AC cans as temporary fix. I did not try to fix it permanently, thinking it would be very expensive. The AC problem is still there, which is very annoying during hot days.
