Well, maybe you can find one at the wreckers, then take it to your aircon bloke to get installed and regassed.Well where's the fun in that?
I've already paid for a regas which is still valid for a further regas (carried forward due to finding the leak) and balk at the likely cost of getting a retail new condenser if I can avoid that by getting a 2nd hand unit and fit it myself.
It's all about the gas in this instance. If there's no gas in the system there's no reason why you can't swap the condenser yourself. I haven't done it myself on a Patrol, but I have on other vehicles. It's definitely not rocket science.The system is empty due to having a shot condenser so there is no issue with gas being released, it's already been released.
I find it strange that this is the first time I've really seen people pushing to have a garage do something rather than the owner! I get that I need a professional to regas it, but given its a currently empty system I'm not sure why there is a reluctance to tackle a component swap at home.
