It it moves in one on the positions, then the vacuum motor is bad. If there is no vacuum at the motor in either position then it's a bad switch at the control head or no vacuum to the switch. I'll look at the hose you pictured me on my Jeep and see if I can figure out where it goes to and I'll get back to you. Keep me posted if you try this fix.

At this point, that should be a no brainer and can't cost more than $20 to do them all.

It looks like a vacuum hose that has come off.

That line more than likely is supposed to be connected to the vaccum reservoir that should be mounted under the battery/ inner fender well area. If you are not the original owner, this vehicle was more then likely involved in and accident and they removed the vac reservoir and left you hanging....

It was in an accident, but I have had the truck for about 8yrs now. And actually until this problem I have actually had zero problems besides routine maintenance for it .None of they problems started until I took it in for an inspection. The cynical side of me wants to think they did something to it hoping I would come back for repairs.

The unfortunate reality is things like that do happen. Hopefully this isn't the case for you.
