Air Conditioning Fault

[AndrewOl]

2010 A207 aircon won’t switch on. Light just flashes a couple of times when pressed and then stays off. Can’t detect the compressor clutch engaging. Thought it was just low gas pressure but local garage checked refrigerant level and was all good. Plugged in my icarsoft and there are no codes. It is booked into Pentangle in early October for them to have a look but I wondered if the collective had any ideas?

AC Pressure Switch

Using you iCarsoft, what is the refrigerant pressure.
A failed pressure switch will not give a fault code.

The pressure was reading zero although full of gas. Clk you were spot on. Pentangle changed the switch/sensor and aircon is all back working. Thanks for your help everyone.
