Morning All - Hope everyone had a good Christmas!
I’m trying to sort the air conditioning on our 2002 Vogue SE at the moment. The last VSE I did wasn’t too bad but this one’s being a pain!
So far I’ve replaced:
Air Con Condenser
Air Con Drier
Both A/C pipes that run along the bulkhead
After doing all of the above I put 2 bar of Nitrogen into the system and soaked all of the connections with soapy water and got no bubbles anywhere. I then took the pressure up to 10 bar and after an hour I’d lost 1 bar of pressure. Over 24hrs I’m loosing anywhere between 6 and 8 bar of pressure in it.
I’ve done soapy water tests over and over on all of the connections that I can see and am unable to find any leaks anywhere. I’ve got the dash out just now replacing the heater matrix so I’ve sprayed the evaporator too and cannot see or hear any leaks anywhere.
I’ve bought some UV dye but as there’s zero refrigerant in the system I’m unsure how to circulate it as I don’t fancy trying to engage the compressor when it’s only nitrogen in the system.
Has anyone got any thoughts or suggestions on where to go next as I’m at a loss unfortunately.
