wrong, section to post this in. welcome area is to introduce yourself and your ride, not to ask for help with your truck. I see you have already posted questions in the right areas so you obviously know where to do so

The hose your describing, I think goes to a vacuum reservoir located inside the fender. There is a small nipple that the hose goes to, which then leads to the reservoir in the fender. I recently had the same problem, which caused my 4WD to not work, and my HVAC to do some funky things. Hope this fixes your problem
