Greetings,

I bought my 97 C280 sport 12 months ago. About four months after I purchased it the A/C output temp. stated to get warmer. I took it in to an A/C shop and they put a half a pound of refrigerent in it and it was cold again. They could not find any leaks. Six months after that the A/C started to get warmer again. I added a can of 134 refrigerent myself and it was ice cold again. Prior to that I noticed that when I accelerated the air volume comming from the vents would slow down. Last week It stopped blowing cold all together. I looks like the clutch is not engaging.

I went to the continental Imports site (http://continentalimports.com/ser_ic40142.html) about using the in dash A/C control to find fault codes. My A/C controler is slightly different than than the one in the article, it doesn't have the red/blue hot cold buttons on both sides. Is there a way to find the fault codes on my C280 A/C system.
