Through the winter, do you leave it in ECO or Auto?

Check its seized or not first mate.  If its seized usual to replace compressor.

To check, remove elec plug on compressor and put 12v across compressor terminals - if you hear a loudish clonk thats the clutch engaging and all is well with this component.

I would check there is a 12 volt supply to the clutch first. If it's not there, there is a relay and a few pressure switches to check.

Good move Kevin - remember now when I replaced old Estate compressor I did check this first - all ok and was in fact seized clutch.

How did you get the pump working? Maybe there's a clue there?

I don't think I've ever come across an Omega where the air con is what I'd describe as "ice cold", though.

I just put some extra gas in under pressure to bring it up to 45 psi and it just kick in with engine running.

Title: Re: Air con
Post by: Michael2.6 on 22 May 2012, 18:59:34

So nobody has any more suggestions?

Title: Re: Air con

You using one of these DIY kits mate?  If so they're krap.  Suspect your problem due to insufficient gas in system - you need an air con specialist to fill system with correct amount of gas.  Air con ain't for DIY mate  ;)

Whilst your low side presssure is about right @ 45psi, correct function also depends on correct pressure on high side (expect around 200 psi).

low on gas usually the pump will cycle on and off if that's happening by all means throw a bit of gas in, I've never had a problem with D.I.Y refills i just wish you could buy them in Europe because it costs me €60 a year to keep filling mine as i'm too lazy to find the leak although it's around the compressor somewhere from the dye i can see!! :D
