There is a Toyota Customer Support Program for this problem. It's not a recall, but repairs to the HVAC servos are free. This is the notice.

Yeah, rear only mainly on passenger side. Are you able to see the tech stream photo I attached I feel like the thing highlighted could be the issue

I can see the data. I wonder where the system gets the estimated temp from? 677F can’t be right. Maybe start with finding and cleaning the temp sensors, then resetting the system with a battery disconnect? I couldn’t find others with exactly the problem with a search.

I’ve had similar issues on my 08 and it ended up being low of Freon

Hello,

I've been having weird symptoms from the HVAC system where certain vents would blow air and others would not work, other times top vents would blow frigid air while the bottom ones would blow lukewarm air. I hooked up Techstream and got the following data, I'm assuming the estimated temp (rear D side) & estimated temp (rear P side) would be the culprits are the numbers are way off, but would appreciate any input/insight on where to diagnose and what to change.

Front seats A/C & heat work fine.

Thanks!
