2010 FX4 Blend Door Problem?

2010 FX4 Blend Door Problem?
Earlier this week when I had the AC on and set at 60 the air on the drivers side is very cold and it feels like the passengers side is blowing ambient air regardless if the passenger controls were on or off and the temp setting. Today the truck would have no air blowing through the dash vents when I first turn it on even with the ac set on max but would eventually after a few seconds slowly start blowing through the vents and can be adjusted to the floor and back correctly after that. I have no clicking noises behind the dash when changing the temp for the drivers side or using the passenger controls. Does this indicate a blend door problem, a HVAC temperature control panel problem, or something else?
Any help with this will be greatly appreciated!

I can handle the repair myself depending on which blend door it is.... if that is even the problem. I do not want to throw parts at it until I fix it.
The truck is a 2010 F150 FX4 SCREW with 89,400 miles. Dual air controls, heated seats with rear defrost if you need that info.
Thank you for your help!

I am being told it may be either the HVAC module, the actuator, or the control unit. The control unit is rare to have this problem so it should be either the HVAC module or the actuator. Can you offer any suggestions?

Thanks glc. I am trying to keep from going to one of my local dealers and paying an outrageous price when I can do the work myself. I just need some help troubleshooting the problem.

Would you happen to have a part number for that controller LBT ?
I have changed both my passenger (upper) and drivers (lower) actuators but am still having a "full heat" situation on the drivers side regardless of where the temp is set. I ramp it up then down and sometimes get cooler air.... the passenger side is fine. I also have sporatic AC functionality.
cheers,

So I’ve been having the same issues on the passenger side. No heat. Based on the threads and the popping noise it was very obviously the blend door actuator behind the radio. A repair shop “fixed” the actuator in that it doesn’t pop anymore but still no heat on passenger side. Has anyone else had this happen? They are trying to tell me that it’s not related to the actuator they replaced but based off of the huge amount of threads describing the exact same issue/solution I’m thinking they just didn’t fix it right. Am I stupid if I take their word at face value on this one?
