Hi, it’s been awhile since I have been on here. I bought 2 SL55 on my travels. Just a heads up when dealing with these cars. The Obsidian black /Berry Red had a non functioning A/C which was fine since I had a spare compressor. Had my girlfriend bring it into my Indy guy and ran codes. It turned out the P/O attempted to repair it himself because everything was clean and the fan shroud was loose. He also installed a new A/C module . I am guessing he thought it was plug and play, reprogrammed it 20 minutes later A/C running. A lesson learned as is you all say check the easy stuff first. I will post pics of them when I return back to Florida. I found out about a similar issue on this forum page 68 I think. I drink a lot lol
