I am wondering if anyone has any experience with the Air conditioning system and the motors used to change the air blend from hot to cold or move where the air blows. Example defrost / footwell / dash vents.

Seems I am experiencing an issue with what I think is the hot / cold air blend motor. With the car on, there is a constant motorized sound coming from directly behind the radio and a/c control unit. I notice the air blowing is colder at times than at others. I have a filling it has to do with this motor that is just whiring probably not experiencing full travel.

Any ideas appreciated.

Thanks!

After a bit more research I have learned the control units are actually called servos. Now the question is how many are used on the GS300's and where are they located specifically.

In other words are we required to take the dash out to change out the servos or can we do it with the dash in.

I found information in the second gen forum. Again thanks for any feedback!
