whenever i engage into 4x4 with the sotf switch my a/c turns off. this has to be a vac leak right? i replaced hoses going to hubs and going to vac pump... didnt fix my prob. any help would be great. thanks
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?
