There is a blend door acuator which moves when u change your settings. Its a electric motor. Down under dash, Will need a mech and a heating and cooling diagram to find where the motor is,

hi ,look under your dash near the blower and find a 4 or 5 wire plug going in near the blower,unplug it and remove the screws holding it in place ,pull it out ,it will be about half a cigarette packet in size when youve got it out in your hand ,this is most likely your problem part ,its a heater resistor ,it controls your fan speeds,it should be a white chalky resistor or an alloy heat sink type ,they come in 2 ways as i've stated,phone a ford specialist junkyard or auto wrecker or a new ford dealer and give them the part number it has on it and your thunderbird specs or ID numbers and you should be able to locate a replacement without too much bother .
THANK YOU for using FixYa

I'm afraid you have the deluxe system,my friend. It has 2 electronic circuit boards that may be going bad. Very expensive unless you can find used or aftermarket.
I hope it's just the blower motor, but I had the other thing happen and I had to wire around it,losing my AUTO temp and blower control. don-ohio

Sounds like you need a blower door acuator motor, which moves to direct the heat to where you want it to be

you have a stock vent valve most of the time the get stock in defrost pull the control panel and check the vacuum lines and regulator

The blower motor resistor is located near the blower motor. It is held in place by 2 screws, and has a wire clip connected to it. Very simple fix.

I hope this helps you, and I wish you luck on your repair.

You have a vacuum leak,defroster is the default position for no vacuum. Check all the vacuum lines near where you were working to make sure you didn't accidentally knock one loose.
If you don't see nothing there find the small black vacuum line that goes thru the firewall near the evaporator and heater core under hood. Trace it back to the vacuum canister and then to the intake manifold to make sure it is hooked up.

There are what they call mode door's these days they have a electrical motor that turnes the door to different posistions...sounds like yours is become broken. It would depend on your expertise in the ac & heating system area to replace the part. Sometimes easy and most of the times the dash has to be removed.

Replaced automatic Control module in dash and module at blower and the blower Still have no heat. Original problem was smoke for vents and no blower help...1994 thunderbird
