I'm thinking my 7.3 has a vacuum leak SOMEWHERE.... My automatic 4WD is not locking in and my A/C blows cold BUT it only works on defrost no matter what position the knob is (Max, A/C, Vent, etc..) which makes me think there's a leak somewhere. Also, isn't the wastegate controlled by vacuum? If there's a leak somewhere wouldn't it affect that in negative way?
I know very little, barely anything, about diesels or turbo engines as I deal with Vettes - but I'm learning!! And I love it!
