I have a bad air mix servo on my 2000 RX300. No noise, no movement...dead. Two questions that I found previously raised but not definitively answered in my search of this forum:
1) Has anyone found a source for a replacement 12v motor rather than replacing the entire servo?
2) Is the air mix servo in the Highlander (or any other Lexus/Toyota for that matter) interchangeable with that used in the RX300?
and a third question:
3) Do the various servos in the RX300 a/c system use the same 12v motor?

The search should have found the post by me with on servo-motor. It has the best possible match, but the min quantity was 1000 units from china. That is a huge risk which I shied away from.
The other issue with the motor is that one has to de-assemble and reassemble with care [arms and the contacts must preserve synchronization.
My search was limited to Mode-servo.
The failure happens with use, so buying a 'used' item has little appeal.
It is a common part among Lexus lines (IS, GS etc)

Agree that used parts are almost not worth it in cases like this, but I enjoy tinkering with this sort of thing so I'm willing to give a motor or even a used servo unit a try if the price is reasonable. The Pull-a-parts around here don't have any RX's and the one traditional yard that has something they could pull, of course, wants to charge almost as much as a new unit due to the labor of pulling. Wish they would just let me at it...
Oh well, I'll dig around for a couple more days before I cave and purchase a new one.
So far, parts.com seems to have the best price. If anyone has found a less expensive source, please let me know.

Do a cross check with IS and GS and if they are the same Lexus/Toyota part number, then feel free to post there too.
One thing to watch out is that part number for the motor (not the Lexus part number) comes in 3/6 and a 12v version.
When it comes to replacing motors, you have to physically match them ... unless you want to carve out the cavity or build the motor up.
