Hey guys, I was replacing my heater core in my 2001 dodge ram 1500 when I accidentally disconnected these five air lines that go to this pneumatic piston thing for the air conditioner. They connect to the thing that changes the direction of air flow be it the feet, face, both, defrost or off. Some of the pressure was released before I could put it back on. Does anyone know what I'm talking about and how I can fix it?

 

It's just a vacuum harness. There is a check valve in the system, so, it holds some vacuum, even when the engine isn't running. Just hook it back up, make sure it is secure, and you will be all set. The mere act of starting the engine will give it some more vacuum to play with.

 

Is the the "thing" you are talking about, that connects to the "thing" that connects to the piston thing?

 

Yes!!! Hahaha
