Poor AC performance Due to Evaporator Temperature Sensor Failure on Mercedes-Benz C280

Problem Description and Possible Solution

The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not turn on, the AC system will not blow cold air. If the compressor is stuck on, the air will be very cold at first, before warming up.

compressor is working but will not get cold
AC shoots out hot air WHEN THE OUTSIDE temperature goes above 90 degrees. It is NOT a hot engine but HOT OUTSIDE TEMP. Three shops 'cannot' find anything wrong with AC as they keep car overnight and in the cool morning everything works great. NOT I hope to finally get this corrected.
a/c goes on for 90 secondsblows cold airthen warm, compresser goes off an blows warm aircould it be the evaporator sensor?
Compressor won't kickin, Replaced with new compressor, serviced refrigerant but no help.
