i love my buick but this problem is awful, i have had this problem repair twice. the first time it was the coldest day of the year an i went to start my car for it colud warm up went back into the building, when i came out my windows were still frosted and my car was cold as you know what. the next time i was in ga on vacation 100 degrees and no air at all. i had this problem repaired two times already and i be damn if in january the damn thing went out again. i've paid about $700 already and i am sick and tired of not having air or heat when its needed the most. so now it dec. and i have no heat so bacislly me and my children freeze every morning till i get another $300 to $400 to repair this problem again and hope it last more than 4 months. i love buick but this problem is to costly i hate to do it but im going to have to get a reliable car that i wont freeze nor burn up in
