It's actually the Mode door. Blend door is for the mix of hot and cool air.

OP, radio and surround need to come out. The front cover of the HVAC system needs to be removed. It's really tough to get out though. I cut a hole in mine and sealed it shut when done instead.

Behind that cover will bethe mode doors. There is foam glued to them at the factory that falls off. It gets wedged in the doors preventing them from moving. Hence you get stuck with only one or two selections.

If there's no foam stuck, then your mode door actuator is bad. That's located right above the gas pedal.
