Ok long story short when I got my truck back from getting studs my mechanic told me that he had to plug one of the vac hoses to get my ac to work and that I needed a new PVH Solenoid for the 4wd to work. I can hear the vacum run when I start the truck but when I connect the hose to the solenoid my ac blows through defrost and 4wd wont engage although the light comes on. Any ideas? Also the vacum pump was replaced a year ago and I checked the hose going to each of the hubs.
