SOURCE: Where is the Blend door
Both are located behind the dash. You have to remove the dash to get to it. You might want to change the heater core while you are back there too. Some will tell you to pull a few bolts and wedge it open just enough to get back there and remove it. If you value how your cars dash looks I would advise against this. Good luck.

SOURCE: will only blow hot air
Did you check for the vacuum line connections? They are vital to the servo motors that open the internal doors in the climate control box. Many times they get either disconnected by the fire wall or they get cracks, or burnt against something hot, thus creating the loss of vacuum power to the servo motors or actuators as you call them. That would be my starting point. Being that issue resolved also check the amount of Freon gas you have in the system from your low pressure side, the charging port should be close to the accumulator or drier. You have to connect a gauge to it, a gauge designed for the AC system, with out it, you cannot determine if the system needs some charging. Some times you can actually get a "kit" from the auto part store that already includes the gauge with the Freon bottle, but you wold be investing in Freon without knowing if you actually need it. The reading with the engine at idle and the AC working at MAX should read between 35 to 50 psi according to the environment temperature. ie: at 70 degrees it should read about 40 psi. at 80 degrees about 45 psi and at 90 degrees at 50 psi. That being the maximum reading, never higher than 50 psi. But before getting to this point I would resolve the blend door actuator issue as you call it.
