Several different systems depending on the YEAR of the car!

Could be....
Klima relay pushbutton control unit slipping clutch bad compressor speed sensor You really need the factory manual, there is a separate book on A/C, with a very detailed problem solving section. Jim

Is this Melbourne Florida or Australia? I'm not sure we'd have the same fusing/wiring on a RHD AU car, and the ACC was optional there also.

It's Melbourne Australia and the current temp as I type this is 36 degrees C or around 97 degrees F.
The OP has some small problem as his car's A/C was converted to R134 in Perth while the car is now in Melbourne. The distance from Perth to Melbourne is comparable from California to Florida. Thus seeing that same repair centre is slightly difficult. FWIW for the O.P., I have just had my W124 260e' s aircon serviced and refilled with gas in Clayton for AU$140.00. Australian Design Rules require proper ventilation to the front windscreen and as such there would be no current OZ specced M.B.'s without A/C. There are subtle differences in the setups for the A/C. Australian specced cars are also fitted with higher specced cooling systems than European cars. Last edited by Ivanerrol; 01-22-2009 at 05:22 AM.

check that the heat is not on because it will win in a fight with the cooling.check the diaphram of the solenoid in the heater valve[called mono valve].simple way to do first check is to use a pair of needle nose vise grips and clamp off the heater hose on the exhaust side and then run the a/c.if this car converted to 134 cooling not that good anyway and heater valve being open will kill it.
