2003 rx 300 not blowing air through certain vents
Only blowing air to the windshield and not the other vents. Won't switch to any other vents. Any ideas?

When you push the mode change button, do you hear from behind dash some sound that indicates it's trying to change the air blowing directions? I am not sure of 2003, only know my 2000 has the mode changing sound even when A/C is off.

Blander door actuator is not working or the climate control unit itself. As it was mentioned, there should be faint noise when vent door move. Can be all kinds of reasons - something stuck, debris, loose plug, bad fuse...

If the front defroster is ON then once again the air will be directed up there.
Make sure the defroster is OFF.
Take the AC out of Auto.
Turn fan to max speed (see the pictured change) and hear the blower going all the way.
Change mode and see the picture change and see if the air out of vents change.
If not then follow the procedure out-lined in Air Mode Servo DIY and see what if going on.
