I was wondering if anyone else had this problem. I had a crack in the AC line in January, 2013 and it was fixed/covered under warranty. I recently turned my AC on and it started blowing warm air again.. I took it to VanDevere Kia dealership hoping it was still covered under warranty. It was not. They charged me $100 for their "diagnostics" even though I walked in and told them what was wrong with it. They told me it would be $390 to fix it.. My fiancé looked under the hood and noticed the line from the compressor just dangling there by my belt.. Is this an easy fix? Do you think I could go somewhere else and pay less than $390?
