I have an annoying problem with the air con on my focus, just wondering if anybody has any ideas as to what it could be?

Basically the problem is that it randomally cuts off? It always works when you first get in the car and sometimes lasts for days before the problem happens again.

When it does happen normally you just give it a few minutes and try again and it works again?

I had a similar issue a couple of years ago which was the compressor clutch working intermittently, I changed it for another one from a breakers and it worked ok. When the clutch was playing up you could always hear the condenser fan running, with this latest problem when the ac cuts off the fan stops too leading me to think it could be some kind of pressure issue?

Anyone got any ideas or things I can check to try and find the problem?

 

Could be low on gas, or the pressure switch has an intermittent fault.

When it isn't working, you could try disconnecting the pressure switch and bridging the wires to see if the fan cuts in.

 

I initially though it was low on gas but the fact it will work for days with no problem makes me think it will be something else?

Thanks for the tip on the pressure sensor. I'll give that a try

 

Get a pressure tester, they're only cheap. stick it on the ac rad and get a reading, if it's fine then source out a high and low pressure switch.. Can probably get them cheap second hand.
