2012 RX 350 Vent Control ***** all inoperable

At 53,000 miles on my RX 350, I have developed a problem with all 4 control ***** on the dashboard, controlling the flow of air from the vents.
They are all frozen, unresponsive to dialing up or down.

I can go to any of the cooling/heating modes no problem.

I checked with my local dealer service rep, he is suggesting recycling the servo motor, maybe this will fix the problem. ( $370 !!)
Alternatively, the servo motor may be bad, or possibly i have a blown fuse?

Has anyone else seen this problem with their 3rd Gen RX 350 ?

Thanks,

Steve in Miami

Could indeed be the servo motors or the blend doors stuck in position. If you opt to pay someone else rather than attempt a DIY fix, find a well-respected independent automotive HVAC shop familiar with Toyotas. You will pay much less and probably get significantly better service as well.

Luckily, I had gloves on and through considerable effort was able to make the wheel move to adjust the air flow. Once I did that, it worked properly.
