this little vacuum line does a lot !! even the 4wd light was not working

 

yup, you break that one, nothing works! that's right off the vacuum pump

 

That would be a ruff one to find

 

hahah trust me i installed the airdog just like in the pic and i lost my cruise and only the defrost worked soo i went back and traced everything out and finally i opened the hood and it was like a shining light pointing to it!!! i felt like a slapped a@@!!!

 

Not only the 4wd light, vacum engages the front axle so the 4wd wasn't working

 

4wd was working , i have to use it everyday

 

yep one vacuum hose comes off it's like the whole truck wants to go haywire

 

Mine rubbed a hole in itself against the trans dipstick tube along the fire wall.

 

Alright well I do have these problems with no fourwheel drive cruise control doesn't work and my heat/a-c is stuck on defrost I found this loose vacuum line that's in the pictures and it's not attached wondering if someone direct me to finding where it's supposed to go thanks any help is appreciated

 

there is a vaccumm pump right infront of your powersteering, it will have a rubber gromet on the top of it that that line plugs into
