I've got a 1986 Mercedes 190E 2.3 that my family has owned since it was brand new. About 10 years ago, i'd say 1996/1997 The a/c quit working, and it was brought to the dealership where the refrigent was converted to new spec (R134a). The A/C still doesn't work. Now the car belonged to my grandma up until about 2005 so she never had a problem riding in the heat, being old and all I guess. But now I'd like the A/C fixed, I've tried adding more refringent while the car is running with the blower running, which comes with the conclousion of cooler air, than outside air, but not cool enough to be considered "air conditioning" at all. When taken to the dealer they hooked it up to their computer, and said there was nothing wrong with the air, but they had a problem with their computer, so there could be an error. They charged me $150 anyways which is fine. Just wondering of anybody could tell me what I might need to check for. Sorry about the long life story.

I sure would like to know what "computer" the shop hooked the car up to since it pre-dates the OBD scan technology.

The typical problem with the W201 a/c system lies with the 1) crappy ND compressor; 2) leaks in the compressor or cooling lines (expansion valve and fusible link); or 3) bad climate control unit.

Any competant a/c shop should be able to tell you if the compressor/clutch is okay and should be able to locate leaks.

I took it to the only certified mercedes benz dealership in kansas which is a place called aristocrat. But thanks for your help, that will give us a place to start.
