Yes take the glove box out. Once done you should see a control that kinda resembles a boot and it has a small white arm on it that looks like a straw and has two phillip head screws that should be removed then disconnect the wire connection to it. Once you do that get a dremmel tool and cut a hole wide enough to see the doors they are right behind that black wall and dont worry its ok to cut that spot out all that comes out of it is air and it wont bother anything. you can take the doors out from there or at least see wuts wrong with it. More that like that thing i said that looked like a straw is connected to an actuator arm which the doors are connected to. You can see if they are broke or the arm just needs replacing from there. Doors up for heat------Doors down for a/c. You will see what i mean. If I confused ya then go to www.heatertreater.net and it will give you a picture of what i mean....
The blend door is part of the heater housing box. It involves removing the whole dash board unit just to remove the heater box.
I would think a blend door motor could be at fault if you have no heat or a/c.
Why would you want to replace the door?
Sounds like the door accuator is the problem.
If you look under the dash towards the floor (if someone is sitting in
the passenger seat, it would be towards there left foot) you should see
a black sqarish box.
That's the blend door motor.
It's a little tough to get out.
Try hitting it lightly , it might move.
