Took the vehicle in because the air conditioning was not blowing cold air and the A/C compressor under the hood was making a lot of noises. Diagnosis was that the compressor had gone bad and needed to be replaced, along with a couple of other A/C system parts. During the course of repairs additional problems were encountered such as some frozen/corroded fittings that would require additional repairs (cost) if they couldn't break them loose properly. Convoy was good at keeping me informed of the progress over the course of the next day, but in the end the fittings would not come apart and the additional parts and repairs became the reality of a 20 year old system. A/C blows REALLY COLD air again and the couple of after repair issues were taken care of quickly and without additional charge. Professional repair and quality people.
