No Air Conditioning Issue
My girlfriends E class C238 Coupe's air con seems to have disappeared.
Set temp to low on the climate control and it just blows air temp. Red LED lights correctly when the AirCon button is pressed.
Checked all 4 fusebox compartments for fuses in relation to any aircon/climate/blower and all are fine.
Car garage confirmed vacuum pressure holds and been recharged correctly.
They have advised to try an autoelectrican....
Come from a technical background and done various bits on cars before so hoping to try help out. Any voltage/power checks I can do on compressor or alternative diagnosis checks to identify the fault?
Any known issues with air con failing on this model.
Thanks for your help.
