I am having and issue with the AC compressor in my Vette. It was replaced in July 2016 and failed again one year later (July 2017). After three attempts the dealer finally got one to work. (GM no longer provided the part)It is now Oct 2018 and the compressor has failed again. The dealer will warranty the compressor but is expecting me to pay the labor. I incurred all the expense for the repair in 2016 and $650 in 2017 for a balancer that most like was damaged because of the compressor failure?.

My question is .... Does anyone have experience with this issue??
Are there any service bulletins on AC compressor failure??

Any help would be greatly appreciated.
