Vaccum issue with A/C

I would look at the inner seals on your wheel bearing/hub assembly. If the inner seals to your hubs is dangling free you are trying to draw vaccum to your hubs but you can't seal the vaccum. So in turn your A/C turns to maybe defrost or to vent? Is that what your asking?

Pull the hoses off at your hubs and plug the ends, then see if that solves the A/C problem.

If it does then you know that one or both of your hub seals are bad.

If it doesn't, then you still have a vacuum leak from a hose or the solenoid valve.

I have the same problem and know that there's loose stuff behind the front wheels. Is there a link to fixing it? I saw a large thread about it some time ago but can't find it now. Still looking though

02 F350 CC 7.3 PS, auto, 6x6, 4.10 gears LB. AFE stage 2 intake, 4" AFE SS exh, 6.0 atf cooler, DP tuner with five stages Eng Temp gauge, EGT guage and Trans temp gauge. J.Woods valve body ATS turbo housing. Cooling sys filter & waterless coolant. NON WORKING POS FASS fuel filter sys. Brightbox headlites. I don't care what they say "There's no replacement for displacement." Don't believe statements about anything being better than a 7.3
GOD BLESS AMERICA!!!!
