hi i have a megane 1.5 dci air con dont work had it regased told it was regased but still dont work
ive done some investigating and found when i press aircon button no aircon. but if i take off the plug to the pessure switch. then put it back on while aircon is on. it starts the fans then after 5 secs the pump starts and all works well. nice and cold and if i switch off with button in car and on again starts working again. but if turn egnition off and start again it dont work again untill i pull the plug again. tryed a pressure switch from scrap yard still the same. any sugestions anyone? ie how to test pressure switch ect

If you have changed the pressure switch, You will not have any pressure in the system unless you regased afterwards, The pressure switch would be on or off, Pressure low, it would stop the system working, save damage, pressure normal system would work. So have you got gas in it. Not, if you changed switch.
