Garage Cabinets, Garage Storage, and Garage Organization

I have a 1995 C280 with an a/c that does not blow cold air when the temperature goes up 77 degrees celsius and higher.  When it goes beyond 77 or in the 80's or 90's, all I get is warm air coming out of the vents.  Tried the auto, lowest temp position with the blower # 4 button with not avail.  I have seen diagnostics for the digital control panel for later W202 but do not know how to check diagnostics for a 1995.

Any help to resolve my a/c issue would be greatly appreciated.

is this the same car with the aux fan always on problem? anyway....check the basics...no a/c freon leaks? a/c compressor seized? a/c hoses ok. do a visual inspection first. hook up a/c gauges...see the values before diving into electrical diagnosis...
