Anybody else have this problem? I like to run the heat through the lower (feet) vents in the winter, and recently it stopped blowing through those vents (at any fan speed). The other vents work fine in any other mode, but nothing comes out of the lower vents. Sounds like a stuck door; anybody deal with this before? 2000 ES300. Thanks.

 

What do you mean "sounds like a stuck door"? I'm guessing you have a stuck or bad servo motor. You should be able to hear a slight whirring noise when you change your climate control directions, coming from those servos.

 

Of course it's working fine now; it's warmed up to the mid 50s here. This occurred when it was about 9 degrees Fahrenheit. I'm guessing the servo froze up maybe...
