OK Ive searched so now Im asking.
I have two noises when I turn on my AC. One sounds like my dash cluster is eating gravel and the other is bubbling, liquid, gurgling, high pitch noise coming from the left side vent area. What is going on. The gravel sound is killing me.

OK so Ive bleed the living crap out the coolant system and still no change. It sounds like gravel every time I change the temperature a couple of degrees then goes away. Change temp and it sound like living creatures eating rocks in my dash. Please help.

Yeah, Its sounds AC related like pressurized liquid but its clearly coming from behind the left side air vent. The rats eating gravel has me frustrated. Maybe a servo motor? Who knows but Im sure Ill get it figured out at some point.

Yup and yes it definetly could be servo gears but that would only before a moment when switching settings. the servo should not be going for any length of time, unless its not moving at all and there is a sensor waiting to pick up its position. These cars are amazingly technical, maybe to much so. I still love it though gs400 is definetly in my top 5 of the 50 or so cars I've owned. When are we going to get together LOL. We need to admire are used time consuming beauties.

Going to have the AC evac'd and charged today, figure it cant hurt right? But what confuses me is the gravel noise sounds like its coming from the steering / dash cluster area and even over to the center vent area. All the servos are right up under the glove box area and towards the center. It seems to do it when I change fan speed settings and change the temp. Sometimes it goes away quickly and sometimes it just lingers around.

I have a gurgling sound coming from dash area as well. When I start moving my car from a stop it gurgles for a second then stops. It seems to do this randomly. The sound actually went away for a while after I received a coolant pressure test, but now it is back. I have had my coolant changed since (when I got my 90k maintenance).
