The air on my 'new' Boxer does not work so I took it to my A/C guy today who re-pressurised the system, which held the pressure OK, but the A/C still does not work. The compressor clutch does not engage. We checked out the temperature control in the cabin and it seems to work fine and we could hear the relay clicking in and out. The A/C guy thinks it is the pressure switch on the drier. This seems relatively simple to change but will need another regass. No problem, but the switch which was listed at £35 (around $50) is no longer avaiable and the replacement 'kit' (???) is £300 ($575). Anyone got any ideas where I can get a suitable pressure switch from?
