Jepp Wrangler TJ 1997
G'day, went for a cruise with a couple of Jeeps to Watalgan, and I got to have a ride in Kingofsideways modded Jeep (very nice), he had his aircon blasting - it working really good. My Jeep had a problem with only working on defrost and not the dash or feet vents. So I had my A/C off and the windows down, sweating (because it was nice warm day).
This motivated me to fix it after we got back home, I started to rip out the centre console aircon.
My thoughts:
1: The Vacuum Actuator vent door arm leavers were broken or,
2: Broken or cracked Vacuum Actuator harness pipes or,
3: Faulty selector control panel or,
4: Blocked or dirty Vacuum Actuator harness pipes.
First I checked the Vacuum Actuator vent door arm leavers, under the drivers seat on the right on your back. The frame is a pain in your back literally (I read on another website that you can take the drivers side seat out and have a look that way) but I was only having a quick look to see if they were all good.
They were fine, nothing wrong with them
, unlike this one from another website:
Next I pulled out the selector control panel, and had a look behind it to find that the Vacuum Actuator harness pipes were not even connected, they were hidden behind the glove box (prev owner must of put them there
).
So I connected them up to the selector control panel and started the engine, but no cigar, the actuators needed assistance to open the vents, when they were pushed in manual with the engine going they would slowly come back out = A leak in the Vacuum Actuator harness No 1 thought. I pulled it out of the selector control panel to find which one was the vacuum tube, the black one.
I followed it through the dash into the bonnet to the manifold connected to a T piece.
With the engine running I could hear a sucking/hissing sound looking at the manifold.
I felt along all the connectors and tubes to feel if there were any leaks, even the one that connects to the brake cylinder res. BINGO, found the problem, the black tube connector that supplies the Vacuum to the actuators was responsible, so I disconnected it.
Flipped it over and found this:
A nice big hole worn into the tube. So I blocked it up with electric tape
, connected the Vacuum Actuator harness to the Selector control panel and started the aircon, woohoo it works!
This it just a temp fix of course, I will buy a new connector and tube.
I hope this guide will help someone in getting their aircon working!

I should have put that suggestion in the first post.
