Well, my a/c compressor has taken a dump. The dealers estimates $1400 to repair. My question is, when replacing the a/c compressor, does the ecu need to be reprogrammed? Or is it just plug and play. I found a few used ones for $250 on car-parts.com and few remanufactures for $500. The dealer estimated the labor at 4 hours ($98 per H) AND $1K FOR THE COMPRESSOR.

Please help guys. Can I just get a used compressor and put it in without any electrical hassle?

Thanks.

 

plug and play.

just don't turn the ignition "on" when the system is empty with freon. or else, the "ec" light will come on and you will need to delete the fault using diagnostic computer.

 

Thanks.

 

Hi i was reading your problem on your A\C and i have to tell you about the joke i'm going through i bought my 99 slk about a year ago the day i bought the A\C was broken i called the dealer (Toyota) they told me to bring it in they sent it to Mercedes to look at it and came back with a 3100 cdn bill toyota choked at that and said will get it fixed but not by mercedes so they sent it out they fixed it..lasted two months starts to leak green stuff and no cold air they sent out again lasted one month i hve it at the dealer being fixed again as we speak.. the first time they changed a seal (1000 cdn..vthe second time they changed th compredssor and a seal..(2000 cdn).now there fixing i don't know what on it ..( who knows how much).when Mercedes first looked at it they said every thing had to be replaced because of metal shards in the system..they have spent mor fixing it wrong and still broken then it would have cost to do the job right..no i'm not paying for it i got extended insurance and their paying the bill

 

Well. I tested the a/c compressor by dropping a (-) into the compressor wire and the clutch kicked in so my comressor works. However, I am unable to put tthe dye into the a/c system to find a leak(I think the psi is too high in the line). I may have electrical problems with a/zc not turning on. I think the only fix the dealer have to to replace the full system. And when theyt charge you $100+ for estimate, they just plug in the computer and tell you to replace all of the parts with bad code.
