I hope I have not missed a previous post for this year p71. Is there a fuse that goes to the blend door?
I can only hope there is one, or sounds like the dreaded blend door or actuator replacement

I believe that all of the blend doors are VACUUM operated, no fuse. Most of the time its a line that started leaking from age, or the rubber in the actuator has gone bad and leaks.

Most blend door actuators are electric motors located on top of the plenum.
