Now the nice whether is here, i thought id stick the air con on for the first time this year - however it doesnt work! I dont think the compressor is kicking in, all the fuses are ok, and ive tried moving the 4 air con relays around but to no avail. The system was charged last June so that patrs ok - any ideas?

 

not much help to you but, you should run aircon for 5 mins a week, all times of year to keep pipes in good condition, other wise they become hard and lose gases, if you had done this ,you would have come across problem much sooner,

 

easy way to tell if the system is low of gas just bridge the pressure switch wires together its the switch on the reciever drier if the pump starts its low on gas it leaks naturaly

 

the system lose gas with no usage as the compressor seals dry out, this is why you should run it for a few mins every week.

 

Yep sounds like the Gas has leak away, good advice about running air con once a week, as that helps maintain it all and prevents air in system too. And also if you had parts changed poss of leak greater if not done properly or as said not used. Willsy
