Try injecting dye into it to confirm for sure. I have a 2013 and mines also stopped blowing cold, I thought was condenser as well. Took it to shop, they ran tests with the machine, it held vacuum just fine, and injected dye when recharged, and was not a leak. Been about 4 weeks now and its back to ice cold. Not sure what caused it, maybe just Freon evaporating over 10 years
but i have not had to go back to recheck for the leak.
