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?

you should have tried pulling HVAC fuse inside truck first to reset actuators this must be done when any are replaced otherwise they do not work correctly. picture shows left side actuator.
