Blower motor only works on 3,4 and 5. I assume its the resistor. Not sure how to get to it. Also when I push button for inside air it comes on then jumps back to out side air by its self. Half to push it 3 or 4 times before it stays.

can buy it at any parts store.
the other issue needs a switch from your description.
