When trying to change from panel to floor to defrost, it will not change.. even if it is off, it is still blowing air. How to fix? How do you check and see if actuator is getting power? Took it off and can move blend door by hand and it works. Don't know if actuator is getting power or not, but it is not turning the blend door.

SOURCE: Blend door not working.

The bleed door controls air temp not where it comes out, dash, floor, defroster, this is most likely a mode control switch problem, that switch is on the ac control head.

SOURCE: air only blows on defrost (windshield)

should be electric and yes your right , the actuator .

if you havnt done this before than its better to pay for it.1 door is posible.2 control switch also might not keep the signal to remain open possible problem on control panel.since other side works and rear.rule of freon shortage.sonds like door or switch.that is electric and need to test resistance on switch and power outlet possible going on and of opening and closing door.or door stuck open to heater side.and not closing all the way.need a expert to check it out.door breaks easy must be carfully.
