Hi all...hopefully this is the place to be and learn all about any fixes needed especially any trade secrets kept under the bonnet so to speak

No..the clutch turns via hand but does not engage when the ac is turned on…need to identify which is the ac relay to test.Does the compressor run?
I took it to an ac garage who put the gauges on and just said ’you have high pressure’…they didn’t say if it had freon or not..I suppose first thing is to establish the high pressure..I have pressed the valve to see if any gas is leased and did.Well... does the AC have refrigerant (freon)? If not, the presostat reads incorrect pressure for functioning and the compressor feed (12 V) is cut off. That's why clutch doesn't engage. It's almost never due to relay. I don't know which is tha AC relay, but you can do some voltage measurements on the compressor feed. And, first of all, make sure there is freon in the system.
How would I know if there is freon as the garage didn’t say if there was or not.I took it to an ac garage who put the gauges on and just said ’you have high pressure’…they didn’t say if it had freon or not..I suppose first thing is to establish the high pressure..I have pressed the valve to see if any gas is leased and did.
"Freon" is a brand name. Used to be used on old CFC refrigerants, Not really used these days as it can lead to problems with putting the wrong gas in AC systems.How would I know if there is freon as the garage didn’t say if there was or not.
Sorry. The presostat is the pressure switch. The one I ment to refer to above, is the one on the condenser.what is a presostat...
