You possibly have a "Blend Door Actuator" problem.
I hope I am wrong. It is a pretty expensive repair, not the part you need but the labor !
If it is the blend door actuator and you do not want to pay $1000.00+ for the repair ( I don't blame you at all) and you can do a little mechanical labor yourself there "is" a way to avoid all the dis-assembly which is involved by.
(Cutting a hole in your heater core box) to gain access to the blend door.
That is what I sure would do, without a doubt.
If you want to know how to do it just let me know and I will get the information of cutting that hole right to you.
