    my heat doensnt switch to the floor and it also doesnt switch from heat to the ac . i had a mechanic look at it and they said everything under the hood works properly in order for the ac to work but it doesnt go through the firewall, i was wondering if it is the blend door actuator that is not allowing the heat and ac to switch?
