Cut air hoses

[bryaniskoo]

What are these two black and white air hoses near the heater core behind the glove box? I accidentally cut them a little.
They don't seem to leak after I taped them up.

These are vacuum lines one goes to the heater core control cave and the other is the vacuum line, the vacuum pulls on all of your dampers that are controlled by your ac and heater controls. Be sure you repair any leaks

This thread helps to explain what happens when those lines loose vacuum, with pictures

Use a piece of rubber vacuum tubing from any parts house to repair them, you don't want them to leak. You will lose your ability to change the climate controls.
