2007 Buick Terraza Question: Why should there be water coming into both sides of the interior?

When the engine is running with the a/c on do you have water running out the HVAC box?

Yes, and no. It varies, depending on how the ac has been running.

It doesn't matter how the a/c is running. When the a/c is on you should and must have water running out of the evaporator drain. Meaning water dripping outside on the ground. If not you have a restricted evap drain.
