2000 Grand Cherokee AC vent issue

We have a 2000 Grand Cherokee. All seems to be working except a slight issue with the AC. It kicks out perfectly cold air but will ONLY blow it out through the front windshield defrost vents. No matter what area setting you try to change it to (feet, front, feet/front, defrost/feet), it always just keep blowing out on the windshield..

Any ideas what is going on here? Is this something I could maybe attempt to fix? I have replaced the stereo so have some technical experience, but not sure if this is something easy or hard (requiring taking apart whole dash)

 

I had that same issue on my '99 Dodge Ram. It was a hardened and broken vacuum line that controls the vents. The line was broken near where the vacuum line goes into the firewall in the engine compartment. I used a length of heat shrink tubing to repair it. It also could be a broken line closer to the vent controller under the dash. Good luck!

 

I figured it out. Sounds about the same. I watched some youtube videos and one guy showed a hose that simply came off in the engine area and near the firewall. Sure enough, I had the same issue. Applied the hose back on to the connection and all was good. While I didn't do this, I wonder if I should glue it on somehow to avoid it falling off again. Or will this not be good and possibly damage it?

Here is what was basically wrong: https://youtu.be/OFhW2GjjVxE

 

Good job figuring that out. Do not glue that hose back on. Either get a new hose or use a small hose clamp or if there is excess hose cut an inch off for a tighter fit.

 

It’s not a high pressure hose, a wire tie would be sufficient
