You are the MAN!! I KNOW that is what is causing the clicking. I thought it was in front of the driver but it could be on the left. It only happens when I turned the car off in cool weather and start it in hot weather. It's definitely the climate control system. I'll go servo hunting and check it out! Thanks a tonne for the info.

I have a 2004 RX330 as well and have the same clicking noise. It is intermittent and seems to be coming from the steering wheel area. I can't figure out what is causing it. I turn on and off the AC, play with the blinkers, steering wheel adjuster and everything else within the area and nothing seems to stop it. Have you had any success in getting it fixed?

Turn the temperature setting to MAX COOL, "park" the airflow, air distribution system in full defrost/defog/demist position, and then turn the system off and see if the clicking doesn't go away

Hi,
 
We also have the clicking, can somebody offer assistance in executing these instructions?
 
"Turn the temperature setting to MAX COOL, "park" the airflow, air distribution system in full defrost/defog/demist position, and then turn the system off and see if the clicking doesn't go away "
 
I think the MAX COOL is acheived by pushing the 'up' button on the TEMP control.
 
I don't understand how to "park" the airflow. Is this as simple as pushing the button with defroster icon, orange indicator light and the word 'FRONT' on it?
 
I also am not clear on this instruction, "and then turn the system off", is this as simple as pushing the button with the fan blade icon and the word 'OFF'?
 
Thanks in advance for clarification.

i just purchase use with 86,000 miles, it drives like a dream except for this faint bubbly gurgling click noise from dash while car is driving. i thought i might be the cassette player with something in there but it's coming from inside the dash area. Any help as i dont want to take it to lexus dealership. no warning light come on, and i believe it still makes noise when air conditioner is off.

Mine has always made a very faint noise (squish-zz-zz-zz) I believe comes from the A/C "reheat" (?) servo. It has never been a problem and it is only barely noticeable when it is completely quiet in the cabin. It doesn't matter if the A/C is on or off, and can even be heard when there is no accessory power. Usually the regular operator of the car is the only one who ever notices it.
 
I believe it is the (vacume operated) servo that closes and opens the flow of coolant through the heater core in response to changes in the cabin temperature.

Hi,
I had same situation on my car and problem was the air vantilation switch control with electric motor, which is can able to find under desh. When switching the air flow position electric motor control the vantilation valve inside the aircondition unit, which is inside the main unit. So, can able to find two switch close each other ( top and bottom ).
They also link together I think. For my car, inside the top switch electric motor gear tip was worn out. so, sometime not in the right position make can not contact with other control switch then try to get contact but slip the gear caused noise. So I remove top switch and open the cover then put some very thinn rubber ( about 1mm ) stick top of the electric motor gear tip to make sure gear not to loose or slip. If top switch is working ok the bottom switch no more making the noise.
 My cas is right hand drive, so switch is on left hand side behind glove box. You can able to find very easy after turn the air condition on and try to change the vantilation position.

Simple temporary fix:
 
Turn the heater to MAX leave it on for 3-4 minutes and turn it off; that will take care of it for days or weeks, when it comes back do the same thing. I know it’s not a permanent fix, but it will take care of the annoying noise and keep you about 7 Benjamin in ur pockets.
 
Good Luck!

TEMPERATURE SERVO MOTOR is the problem. You will eventually have to replace it. It is a costly item to be installed. If you can do it yourself, it would be cheaper.
