Best way to get the torque shaft for the tcase back on the body side? It popped off while I had the tranny cross member off.

Strange Situation with Air Conditioner
Hi Guys
I am really confused. When I turn on my air conditioning, it starts fine; but while traveling on the freeway accelerating the air almost completely stops. As soon as I take my foot off the gas, the air will start blowing again.
Anyone ever have this problem? I don't even know where to start looking for a problem like this.
Any suggestions will be greatly appreciated.
Thanks Roxanne

It's not going away. It's going to defrost. The actuator that moves the blend door is vacuum operated. There is usually a busted vacuum line under the battery tray going to the vacuum cannister.
Should be pretty easy to find.
What model Jeep do you have?

This is typical of a vacuum leak. The HVAC direction door is operated by vaccuum from the engine, when you stomp the pedal the vacuum that your engine is pulling goes way down (has a lot to do with that giant hole you opened in the throttle body). The factory installed a vacuum reservoir to help with this. It is a black ball that lives inside your front bumper. You'll see it if you take the passenger side end cap off. It's common for these to crack or have a problem with the line that feeds them.
