Hello everyone,

I have a lexus GS350 2012 with air damper/servo. When I start the car, the climate control unit doesn't respond till after a min and all setting return to factory setting (temp, recirc, etc). I use diagnostic tool Techstream to find there is code B1443 (Air outlet Damper Control Servo Motor Circuit).
I checked online but it doesn't tell me which servo is the air outlet. I went to part supplier and asked for servo motor and I saw this diagram for servo motor location. The car got around 10 servo motors in total, 4 on driver side and 5 on passenger side and one last is on the blower box to change from outside air to re-circulation.
The guy at parts shop said there are no names for these motor although I told him I got the code and info from techstream so I am not sure which servo to buy. I went back to my car and run the servo calibration under utilities and I check the bottom servo motors on driver and passenger side ( top servo can't be seen unless I remove dashboard).
The servos were working fine all turning so what should I do? can someone tell me if there is default names for each servo like mode servo, air mix (hot/cold), etc?


Thanks in advance
