A) the only reason they won't clear is if the parking brake isn't adjusted properly and it hits the floor when you press it. (as in it doesn't work at all)
B) if you adjust it properly, it won't hit. It will also work all the time when you need it.

There are 2 styles of kick panels half style and full. Heater vs AC doesn't matter on either as one is manually activated the other is control operated. The Vent has nothing to do with the kick panel pod.

This is the half style:


This is the full style:
