I am having problems with my air conditioning again. My A/C is blowing warm air and this is the second time I have had this problem since buying my 2015 Sierra less than 6 months ago. A few months ago I had the exact same problem and my dealership diagnosed it as a leaking hose and all of the freon was gone. They had to order a new hose and it took a week for it to come in. They installed the new hose and added more freon and it has been fine for the past 3 months until today. This morning I noticed that the air coming out was warmer than normal even though I have the A/C set at 65 degrees. It was fine yesterday. I am going to monitor it and see if it gets worse and if so make an appointment to take it to the dealer again.
Just wondering if anyone else has had to replace the hose or had a freon issue with their 2014 or 2015 Sierra / Silverado?
