I just want to clarified the servos parts # and the location before driving in to DIY! RX300 2001
Lexus Parts #
87106-30371 Servo Mode
-48020 Air Mix Servo
-30390 Air Recirculate Servo
All of the above 3 Servos locate on the passenger side?
What about Driver side? are there any Servos locate on the driver side?

Majorities people replace Servo Mode and Air Mix Servo or you have to replace all 3 servos?

Thanks

 

Servo is generic name for a motor that moves (by turning) some object to a certain point with control.

I have spotted one which looks like a servo on the driver side.

The reason the air-mix and air-mode servos get the lime-light is that they get used most of the time. Here in south the air-mix mostly stays on AC and survives a bit longer. The Mode gets activated many times over during a drive [Auto mode keeps determining what is best].

Since they are expensive around $150 or more, I would suggest service and replace the one that needs to be replaced and leave the other alone. No point in tinkering with them ... the plastic clasps are meant for one time use only.

Yup! I did the clean up on the servos today Air mix servo was fine the noise came out of the Servo Mode got that taken care of, it not making noise anymore but you never know! next time if I have to replace it I know what to do It takes me around 2hrs for this project it's worth the time. Maybe 1hr next time!
Run in to some minor problem but after reading others members posted I figure it out, 1st the moving arms then the motor. Over all it was great thanks everyone that posted their experiences and write up the procedure!
You guys ROCK!!!!!!
