I have 2003 GS300 with nav. No power to blend door servos. Stuck on cold. Servos are good. What else could the problem be? Is there a cabin temp sensor?

 

There is a cabin temp sensor, and they do get clogged with crap. There is a thread I. The how to section. But it’s in the dash under the ignition, by the drivers right knee. If you remove that panel, you’ll be able to unplug it, and it will come out with the panel, so u can pull it out, clean it up, and see if that helps u out. So the servo was working correctly? U plugged it in and tested it before bolting it back into position?
If the servo is good, when u plug it in, and cycle the key, the servo should run from 1 side to the other and then park in the original position. It should do this even if the temp sensor isn’t working.

 

Yes, the ds servo was/is working. I’ll check the part you mentioned.

Thanks
