Cabin filter blend door broken

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Your question requires hands on troubleshooting. One cause would be the door and plenum itself being fractured. A second possible cause would be the blend mode door actuator being faulty. A third possibility could be debris causing a problem. Hands on inspection is the only answer here.
