Thanks for your reply. As I said before about the conflict part numbers from different manufacturers, I was right that none of these parts were the right ones. So, I took it out and I found out the exact replacement part. 4 seasons HVAC heater blend door actuator # 73371 from Carid. Com, $ 64.00 with free shiping (also Bay $70.00 to $84.00, Parts geek $61.00 + shipping) It fits only old body style models. It's located on the left side of the bottom of the heater box. There is an electrical connector visible and 3 screws. Unplug the connector and remove three screws, the unit comes down and you expose a metal bracket (panel). You can use your finger to move the bracket in or out and that changes the position of the blend door that brings hot or cold air into the cabin. If you don't mind the pain of removing the old part from the bottom of the heater box with a mirror you don't really need to remove the glove box. On the other hand, if you remove the glove box you have better visibility and also you have the chance to replace the cabin air filter. If you replace the part be sure that the metal rod on the plastic bracket fits inside the groove of the exposed metal plate. Connect the electrical plug and start the car, let it warm up and use the temperature knob in your dash panel to change cold air to hot air inside the car. That actuator controls only the temperature not the direction of the air to the vents. If that is the problem, then this is a different animal, and you will need to find out the right actuator ( I believe it is the blend door mode actuator) and the location of it in the HVAC system. Thank you again for your help.
