Ok check the actuator and linkage where I have pointed out on drawing. See if it's getting power or not but before you do that try pulling HVAC fuse for 60 seconds with key on then reinstalling and waiting another minute. That sometimes resets that actuator to work again. If it's getting power then you need a new actuator or blend door is broken I coldn't get all of the pic in tosend.
