Hi all, any help is much appreciated ![Thumbs up (y) (y)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
The aircon in my Twingo 2 petrol is acting strange.
Turning aircon on starts the pump with the usual click. Fan runs, the low pressure pipe is clearly cold with condensation and cabin air is turning cold. After a short period of time the cold air disappears but the pump etc. is running fine. The low pipe pressure is 30-40psi as recommended but the pipe is no longer cold. I have tried with less and more R134a coolant without any change.
Today the system was emtied and refilled. Compressor starts fine with a click but the fan is not running and the low pressure pipe is not turning cold. Fuses for the fan is checked and OK. The fan runs fine when the engine requires it.
Can this be related to the pressure switch alone? Unplugging the switch (high pressure side at the drier/condensor) keeps the pump from starting. Plugging it in when everything is running the pump starts but pipes not turning cold
