No A/C from Dash Vents

So I am having troubles with the A/C in my TJ. Like the title says, I can't get the A/C to come out of the dash vents, it only comes out of the windshield defrost and feet vents.

Did some research and had a mechanic look at it and they said it wasn't any of the vaccum lines but that it could be a switch. What "switch" are they talking about?

Thanks

check the 3 vacuum actuators under the dash. They should move when switching from different vent positions.

Turn your a/c on and look at the actuators and arms while you change the vent settings. They should move accordingly:

My guess is the hose under your battery is cracked. Mine was. I just duct taped that sucker today. Instant fix.

Located under the dash on drivers side against the climate controls. It's a pita to get to with both hands. To the original poster it could also be the plastic arm the actuator moves to control the door inside the duct. Recently replaced mine; found it on eBay for $11. Best of luck to you.

I pulled out my driver seat to make it easier to work with.

Here is how it looks under the dash of my 97. I found out that I am missing the floor actuator. The PO must have removed it and never put it back.

I have the same problem but as long as the defroster works during winter I'm fine with it. Who needs AC when the doors, windows (soft uppers) and top come off . But in all seriousness if I had the time to tinker with it I would. Good luck.

Okay so I didn't want to leave the thread without saying anything.

Thank you all for your help. I found the issue with the A/C.

In the picture below, plug (5) wasn't plugged in and rather loose.
I plugged it in and just fastened it so that it won't come out again.

THanks for all the help!

And the "mechanic" said "it wasn't any of the vacuum lines". I'd find a different mechanic.

Plug 5 is underneath on the passenger side about half way between the tire an the cab.

I took mine in and while I was telling the mechanic about about my ac not blowing out the vents he reached underneath and plugged it in. Quickest I have ever had something fixed.
