I took the AC evaporator out of the car to try and find a leak. It is never in an easy place to get to is it? I couldn't find any damaged area as I had thought but instead I found that I had neglected to tighten a factory assembled fitting. It was tight but I turned it at least 3 rotations to snug it up. The system worked a little bit(never really cold) and held a 30 psi vaccum, but now the system has no charge so I took it apart when I spotted oil dripping from the blower fan. My question is how to test the evaporator out of the car? Do I need to pump it up to 100 psi and see if it bleeds off. Do I need more pressure? , less pressure? I am really new to the ac world. I just don't want to put it back together with out testing it.
