Spraying w soapy H20 has bubbling right next to firewall when AC is set to full see pic for bubbling area at firewall/low side hose. Q1: could the bubbling be blowback from fan inside firewall/dash? Q2: If I see bubbling when AC set to full why is there not enough presssure to pull in refridgerant / or Q3: If there is no pressure does a vacuum have to be pulled first? I want to confirm leak with dye. Q4: What kind of connection is that in the pic? Is it 2 threads so need backup wrench and how tight should they be and can I unscrew and possibly replace o-rings? Finally, could I be missing something else to look at?
have the same problem?
