I took my car in for a factory recall on my 2004 Tahoe for the HVAC unit which would not fully function on 1 or 2, but was working great on 3,4, and 5 for a/c and heating. They replaced my factory recall on this unit for me; however, when I took my car home I noticed that my a/c would not work on my driver side, but was working properly everywhere else in the vehicle. A friend who looked at my vehicle said that it was probably a flipped solenoid from when they had done the work on my vehicle, so I went back to them since it was pretty strange that this broke down on me immediately after having them do some FREE work on my vehicle. However, when I got there they informed that it was not a solenoid but they knew immediately what the problem was and that it would take at least 8 hours to get to problem just to diagnose it. They also informed me that it had nothing to do with them replacing the HVAC system and that this was just some crazy coincidence. They also told me that it would be very expensive to fix the problem and that I was SOL. I took it in for a small recall and now I have $650 fee just to look at it even though my a/c unit worked completely fine before this work was done now I have no a/c and only scumbags to work with. I suggest that if you have any recalls to be done DO NOT take it here they will just send you in a loop and make you pay for it! We all know how MedVed chevy can be untrustworthy, but this is on a whole other level. This happened immediately after they worked on my vehicle and is just ridiculous that they won't take credit for their mistakes/what they did to my vehicle! I suggest going anywhere but here if you need to get work done on your vehicle! P.S. I am a 25 year old single white female that they thought they could just take advantage of, of course, big surprise there.
