Question '98 SL500 A/C Stopped Blowing Cold

Its another one of the never ending R 129 (not only)issues. I took her for a 30 miles drive last night. I had the A/C on at the auto mode and it was blowing cold air without any problems. Suddenly , the EC light came on and both AUTO and EC lights were on. It was then stop blowing cold ,it just blowing air.
I turn it off and then back on by pressing the AUTO button but the EC light came on at the same time. I pressed the EC button but the EC doesnt go off.
Only if i keep it down for more than 6 sec, then it goes off and only the AUTO stays on but still it doesnt blow cold.
I ve noticed that the fans behind the grille do not engage.
I had the test 20 minutes after i turned off the engine. I took a 30 miles ride before.
I will take the car for A/C charged up but if the compressor is not working they wont be able to do the work. Correct me if im wrong on this one
