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.
Two possiblities. The freon charge levels will need to known on both the low and high side. with a good unit running the low side with the engine reved up should not be less than 25 PSI and the high side can be 175 or as high as 225-250. if not your looking for the problem, if the low is too high and the high is'nt very high the compressor likl;y to be bad if the low is too low and the high is too high the comdenser is clogged or the air flow might not good though as the fan or dirt not going though. the orfice tube could be stopped up but if it is the compresser is failing. and parts are flying though the system. high on the low side the system could be containated with moisture ( too much in the system ) Evascate and recharge may get ti working playing carefull attention to the charge rate astoo much freaon can do the same thing.
copressor is charged the blend door will not switch over to cold side and i did replace the actucator is there a code that needs to be cleared
No any codes to do with the heating and air conditioning system will be cleared just turning the key off but some non functionality codes ( they don't inhibit operation) codes can be cleared just disconnecting the battery. Most of the time this is'nt nessary. If the blend door is'nt moving you can removed it and plug it into the wire and with the car running turn the control to hot and cold the blend motor's shaft shoul move If it does move the shaft that the motor moves with your finger to see if it will move. This shft is bad on breaking at the end where the motor fits into it and the blend door ( sometimes) can be repaired or the entire blend box assembly ( on some cars) has to be replaced as the blend door is'nt sold sapartly. If it's blowing hot when it;s running turn the dash control to hot with the motor plugged in and then install it then turn the control to cold while holding it in ( you shoul fell it turn If it pops of jumps out the blend door is bad and your back to replaceing It.

SOURCE: Blend Door Actuator possibly bad
Not to difficult but you may need to get smaller tools to make it easier or possible depending on the tools you have now.
SOURCE: Blend door actuator possibly bad how hard is it to fix or replace?
usually it is in the dash and the glove box needs to be removed to get to the actuator.
