Of course, with Brisbane temperatures heading up the 'Rage's aircon decided to stop working on Saturday. Has been working fine, lovely and cool, up until lunchtime Saturday, then noticed no cool air coming through.

On pressing the AC button the revs dip as the motor takes up the load of the compressor, but no cool air. Appears to be air/fluid in the sight glass. Checked fuses, they all seem okay.

Had the little fella in the garage yesterday and noticed no clicking from the relay box in front of the driver's side strut tower - pulled both the relays and there seems to be power to the relay bases. So, next step is to replace the relays, but stuffed if I can find the units in question - have been googling away with little success. Found a unit for Kias that looks to be very similar -http://ishop2.cooldrive.com.au/products/PR5010

The units in question are marked as follows:
OMRON
09-72845
12v 20A
0427D6

It's a 4 pin unit, with the pins in the following arrangement:
- -
- -

The exterior's fairly similar to the unit I linked to above. Anyone know where I could find a couple. I'd like to try and replace the units before putting the Halfacar into an aircon specialist.

probably just needs to be re-gassed

Would have thought it would have gone gradually if that was the case. Have given up and will put it to an aircon specialist.
 
its not the relays or else it wouldn't start up at all.
could be a leak in the gas line somewhere to. though i doubt it.
the gas has a distinctive smell so you would notice if it leaked.
my bet is still as above
 
just take it to an auto elec lol... if its low on gas, there will be a reason why, it doesnt just vanish lol.
the compressor can cut in on minimal gas, but wont get cold, and if its cutting in theres no issues electrically. (eg relays are fine)
 
Its not hard to check whether the compressor clutch engages or not.
You can check it with the car off too.
