drivers or passengers side of the vents are not working for AC or heater?

It is an easy actuator to replace it is held in by 5.5 mm headed screws.

Passenger side will not regulate temperature has dual controls passenger side when it seems to work is at least 10 degrees warmer most of the time if you turn the temperature up it will not turn back down . Looking for actuator motors there are several listed guess each one goes to a different part of the system. SO which one is bad and where is it located? If anyone can help thanks....

Yes the blend door actuator you are looks for is the easy one. On the bottom here is a guide with a video that will show you how to get the job done.
