Aircon EC light constantly lit
Hi Guys,

I have the analogue aircon control unit and the EC light is permanently on. The compressor refrigerant is full.

I have been reading about this issue when other forum members experienced this, and at times it was solved by replacing the evap temp sensor.

I just want to find out if my car also has the evap temp sensor? I drive a 2001 C180 (m111 non-kompressor)

It could fail for a number of different reasons. You need to hook it up to a scanner that can talk to the climate control and see what codes are stored.
