Finally have time to feed my NICO addiction.

Its not a big deal but theres this one thing that bugs me. The heater and A/C work at all temps!!!

but when the vents are set to the foot... I get little to no air blowing. Defrost works fine. It wasn't like this before.

Is that what I have to pull out the dashboard for? I have changed that little motor behind the radio that adjusts the temperatures, it used to make noises but worked fine. I was also messing with the pieces and everything seems intact (not broken).

Where exactly are all the mixer doors? A friend was telling me how a hose was out behind his dash on his car. Could that be my problem too?

Frequently the doors are operated by vacuum (lower intake pressure) lines.

Let me study the FSM as I haven't more than glanced at this section.

The doors are operated by tiny servo motors.
