hi, my air con's not working, its a 2001 406 2.0 hdi 90. the fans come on but the compressor clutch wont. i checked the pressure with a guage and its just on the green/blue mark. i went to halfrauds to get a refill can, then when i got in the car to come home to top up the air con was working, so i topped it up and it stayed working, turned car off went back to it several hours later and it is not working again.... f-ing thing.

ang ideas??

thanks

Next to check are the plug and socket to the compressor clutch.
They may benefit from a clean.
Check that 12 Volts arrive at the socket when the aircon is turned on.

bit of an update, still not working, im getting 12v at the compressor plug with it disconnected but as soon as i reconnect it i get no volts at all. disconnect it again and there is 12v again. stripped back the poz wire and put a feed from the battery and the compressor works. any more ideas please

thanks

Try with a test lamp instead of a meter.
That will give you an idea of the current that can flow.
Probably a bad connection upstream.
