Changed the mode door actuator because of a buzzing noise when you depressed the defroster button. Now I cannot get any air out of the floor vents where I did before I changed the actuator, all other modes are working as usual. I have tried a different actuator same problem and have tried several different ways of calibrating the system no change. I am open for any suggestions.

Thanks

Pull HVAC fuse out for 60 seconds inside truck you need to do that when you replace an actuator so they reset. Do it with key on then reinstall.

Thanks for the quick reply. I did find the problem one of the cam door levers was dislocated. Once I got it on location the system worked perfect.
Again thanks for your response.
