original owner 2005 edge, heat control stopped working overnight.. blend door is good- tried new blend door actuator it will not move also,, replaced center hvac control unit (hot-cold knob) did read dc power at actuator connector,, checked all wires, fuses and connectors that could be reached,, getting frustrated,, using an actuator part rigged a push pull rod to get either heat or ac. so the truck is drivable (it is been my daily driver,)
