Air con sensor. Hi all just joined here and have a problem. Who doesn't. Air con stopped working today just instantly. Had a new condenser rad fitter months ago sonot that. Took my l320 2005 to be check the charge and its full. Any ideas, could it be the pressure switch or something else.
 
Could be lots of things, is the compressor drive belt still there? Check the relevant fuses.
 
Yes.

If its got the correct gas and it all seems to run as it should, it could be the expansion valve. if you can find it "tap it";)
Ours (L322) was initially diagnosed as compressor, but it was intermittent. After watching live data on our IID, the compressor was fine and it turned out to be the expansion valve.

As said earlier diagnostics is the easiest way forward but be carful they don't replace expensive bits that don't need to be replaced.

Thank you but it's now doing my nut in with this weather. Just pu gauges on and the pressures are equal with the engine on and off. HELP OM MELTING
 
Is the compressor clutch working, Is the center of the pulley turning when you switch it on.

You should be able to hear it click when you switch it on.

I don't know your car, but on the P38 it's a case of knowing where to look. If you locate the electrical connector for the clutch, you could put a meter across it to check that there is voltage to activate the clutch. Just a thought, on the P38 when the aircon light is on, the aircon is switched off, Land Rover logic, could be the same on yours?
