1999 Lexus RX 300 clicking sound below glove box on AC system

If you take the glovebox out, you can see the air inlet servomotor on the left side of the blower housing. (SEE DIAGRAM)

This is very likely to be what you are hearing. This is a quite common problem. This servo is electronicall controlled. When the HVAC is turned on, the servo is supposed to go through a "full swing" to test itself. Many times, things (papers, napkins, drinking straws, etc.) from an overflowing glove box get jammed in the recirc-air flap right behind the glove box. when this happens, the servo cannot make a full swing and sometimes it damages the servo, which continues to attempt the full swing and keeps clicking because it is stripping its internal gears trying to make it happen.
You will most likely have to remove whatever it is that is jamming the door and replace the servo.

No funciona el ventilador

The flaps that control the ventilation are either cable or vacuum servo controlled. Have someone operate the controls, and try to watch if the cables or servos move properly. It is probably a broken or loose cable, or a broken vacuum line or diaphram.
