There is only 1 blend door actuator located on the left side of the HVAC air distribution housing under the instrument panel. See attached image. Under the temperature blend door actuator there are 2 temperature blend door shafts linked together by lever arms. Make sure these are attached to each other and operate together.. . . I replaced both thermostats, both blend door actuator and blower motor and recharged freon. And now driver side is blowing hot air and passenger cold air.. . . .
