Ac problems

[Thaiyaris]

Hi guys,

So had my ac clutch changed about 6 months ago. It's now stopped working again. Different this time though.
Turn on the ac, revs go up theres current at the ac wire to the compressor.
Pull the fuse and the revs drop.
But the ac clutch doesnt move not even a millimetre.
Seems to me that the ac ecu is stopping the clutch from engaging .

So where should I start with diagnosing the problem. Please don't say go to Toyota the techinchians here in L. O. S are about as useful as a wet rag., a blunt knife or a a wife who no one longer puts out, cooks or cleans. 😂

Thanks for any help you can give.
