Technical 500x 65 plate compressor relay

[Ks22]

Hi, can anyone point me in the direction of the relay for the ac compressor clutch, it’s a 65 plate 500x
The clutch doesn’t kick in when ac activated, gas charge is all good and fuses look good but haven’t tested them yet.
Thanks

Only just seen your post. I have had one AC compressor replaced under warranty. Now have done 70 k and compressor shows same fault as yours. I cant find the fuse bur suspect the compressor has gone kaput. Its a denso unit. Did you fix your problem? A new compressor is 250£ gas recharge about 120£ plus all labour - seems an expensive job for what seeems an inherently weak component.
