I have a 2012 chevy cruze that I bought from Richardson Motors in Dubuque Iowa which is a GM dealer in 2015, after I had it a year, the Ac fan started running loud every 5 sec. I took it there they said it was normal, after awhile I took to mechanic and they put in new Ac fan and altenater, had about a month and fan running high again, took it back and they replaced fan again, took it to another chevy mechanic and they said that no codes were coming up ,but some reason the fan is only running on high..I am getting frustrated along with not knowing what is wrong with my Ac fan. The dealership has been awful, won't help me at all...anyone know what's wrong
