I hope you have had better luck than I with your a/c problem. Took my 2013 Volt to dealer with Check Engine Light and a/c blowing warmer. I was wondering about that strange smell in the car (before the CEL)but choose to ignore it. When I took the car in (after reading the forums) I had an idea....I had a leak. I got quoted $1900 bucks. Damn! I love my Volts ()this is my 3rd) but why can't the cost of repair be cheaper?????
