AC intermittent failure
Please forgive me if this has been covered in another thread. I looked but couldn't find anything. I have a '15 W205 w/ 54k miles. Last summer the AC would sometimes take a long time to get cold/compressor to kick in. The car was under warranty so I took it to the dealer for service. I picked it up, and the service writer told me that they had replaced the compressor. I got in the car to leave, and it still wasn't working. I talked to the writer, and he told me to pull the car to a particular location, and they would get me a loaner to drive. When I put the car in reverse and backed it up, the compressor began to work, and the air got cold. I picked the car up a again a few days later, the writer said that hey had replaced a switch and a control unit and everything seemed to be working properly. I drove the car and about a month later it began to do the same thing. At this point the car was out of warranty, and I decided to address the issue in the spring time (now). I called the dealer and explained what had happened, and he wasn't very positive about getting MB to handle the issue, due to the length of time (my fault). He did say that if the parts were defective that he could prolly help me out. Has anyone else experienced this? Is there anything that I should check before I take it in for a costly diagnosis? Should I skip the dealer all together and take it to a good independent shop? Any advise?

Strange indeed. Why didn't this dealer fix this A/C right the first time and once for all? If they did a good job why did it stop working again. My dealer has one year warranty on its repairs. I thought it was a standard MB practice. If the same problem comes back again within one year of fixing it they fix it for free. I think you need to escalate talk to the manager tell him the fixed the car twice and the same problem came back again. Why do you have to pay for their lack of skills and quality work?
