Aircon repairs - seeking confirmation of correct parts

[Mazda6JW]

Hi All,

I am currently shopping for parts to fix my non-functional air conditioning (UK model, 2008 2.0 Diesel Sport GH MZR-CD); I have already found a secondhand compressor and bought a new condenser including o-rings, which came with it. I need to buy a new a/c pressure switch and the two o-rings that sit over the ends of the pipes where they go into the compressor. I know the part numbers of the o-rings (BP8J-61-J17 and GJ6E-61-J19) but they seem to be ridiculously expensive if buying the genuine Mazda ones (unless you happen to live in Belgium, Japan, or the UAE) - is it possible to find generic (non-Mazda branded) o-rings the same size and spec at a lower price in the UK, and if so, where is a good place to buy them, please? As for the pressure switch, I think the part number is either B01A-61-503 or GJ6A-61-503 - please can someone confirm?

Thanks, John

I bought the O-rings from a Mazda dealer, but the pressure switch doesn't seem to be available. Is there any way these switches can be tested (system is currently empty), perhaps off the car on some kind of test rig?

I've repaired my aircon system (with a used compressor and new condenser) - I've had it re-gassed and the specialist said my work to replace them was good (no leaks). The problem we noticed is that there is a rattling noise when the a/c is switched on - we saw the magnets working and the vent air is cold, as it should be, but noticed the magnets do slip a bit (I should have checked the bolt was tight before fitting the used compressor) - is this likely just a loose bolt (the magnet plate fell off my old compressor) or could it be something else, e.g. corroded plates within the clutch, so magnets are not strong enough to hold it without slipping.

Any suggestions are most welcome. Also, can magnetic clutch / pulley issues be resolved without taking the compressor off the car (so the system doesn't need to be degassed).

I've attached a video, where you can see the slipping, and hear the noise.
