Wife’s 2007 Pacifica has a leak in the AC system. I put gauges on it yesterday and there’s no pressure at all, so it’s completely empty.
I’ve read mixed reactions to the idea of hooking up shop air to the system to pressurize and listen for leaks (or use soapy water). The criticism is that this introduces moisture into the system. Others push back by saying a big leak means the system already has regular ‘atmosphere‘ air in it, and you’re going to pull a vacuum anyway once the repair is made.
Any thoughts on this?
And if I don’t DIY the diagnosis, is taking it to a pro for them to use nitrogen the only other option?
