Question Vent problems

I have 2005 TJ, my problem, the air vent is only working in the defrost mode.
The a/c, heat, and air all work. Can not get the air to come out of the dash,
only coming out of the defrost vent.

Thanks for any help.

you probably need to replace the switch behind the dash.. Most people say to replace the switch behind the fan settings dial, but I had to replace that one and the one behind the AC/Heat/Defrost/Vent dial as well to get the air flowing properly, its surprisingly easy... Think it took me 10 mins total time to replace them... Both switches only cost about $52 from the dealership... Here are the instructions that I was so kindly provided from distortedtj and others in another forum...

I replaced both switches on the back of the box...

distortedty also posted pics that are great step-by-step instructions;

of course... I could be wrong... did you have a melting plastic smell at all?

Vent Flap

Yeah, I have had the same problem with mine but not permanently yet; especially in the winter when it is cold. I believe there is a flap in there somewhere that redirects the air; you can hear it open/close when you change heat/cool settings. I would like to know exactly where it is and how to get to it so that I can see what can be done to maybe lubricate in some way to prevent it from getting stuck open or closed. Does anyone know?
Once you are perfect you can judge me.

I was having the same problem with mine, but it turns out the vacume line going to the manifold came undone. I just had to plug it back in and everything works great now. It is a long vacume line that runs from the fire wall to the intake manifold of the jeep. Just thought, it would be an easy check.
