The fresh air-recirculation control is operated by vacuum. You may have a vacuum leak in the tubes or connection behind the climate controls.

I've not had this problem, but there are several things that can cause it. The most likely is a supply line to the heater controls, or the controls or actuators. The FSM has a description of the components, as well as how to test each system. You will need a vacuum pump to run the tests. The section you need begins on page 24-13 of the FSM. Good luck!

That's hard to answer without seeing it. It is vital for two reasons. 1 It provides vacuum to allow the climate control to work properly, 2 It is a vacuum leak. How are the lines damaged? Are they pulled out of a connector or are the lines themselves broken?

If it's a puncture from testing for power. You can dab a little weather strip adhesive or even super glue over the hole!
