A/C blowing hot air

My truck will blow heat out of the driver side and A/C out of passenger. I have the dash torn apart and have the one above heater box out and unplugged the one to the left of the air bag and nothing changes. I am planning on replacing them all to make sure I get the problem but cannot find a good picture of where all the actuators are at. Is there some place to find them or anyone know exactly where they are?
