The AC on my 2001 Ram 5.9L works well, nice cold air. Only problem on MaxAC (or anything else, doesn't give much hope for heat either) it only comes out the floor and defrost vent.

I've read it may be a vacuum hose. My question is where should I be looking for a vacuum hose?

I get some air flow out of the regular dash vents, just a tiny bit.

Any helped would be appreciated.

 

The vac lines are all on the passenger side of the intake manifold. Read this https://dodgeforum.com/forum/2nd-gen...ild-vents.html
