my 94 c280 at idle some times the a/c will shut off and lockout the digital display reads temp setpoint and the control panel leds goes off the only way to get it back on is to shut down the car and restart very erratic does fine if the idle speed is kept about 750 or crusing down the highway mechanic told me that if the belt slips it will shut down and lockout sometimes runs months and never lock out but when it does start locking out it will do it without the air on with the control panel in the off position several times in a row then start operating normal i just turned 90000 miles and currently have no other problems very annoying any answers out there also where can i get a manual on these cars.Reggie
