whats this noise ?
i have a 98 gs 400 and everytime i turn my car on i hear like a crackling type of noise coming outta the air vents ? what the heck is that/?

my guess, and it's just a guess it could be the gears inside the servo motors that operate the direction of the air flow...I had the same sound, replaced the servo and it disappeared, part runs about 150...the plastic parts inside the motor get out of line and make a grinding sound. Are any of you experiencing air flow, or A/C Heat issues? Do you hear the sound only on startup or also when you switch airflow?

Clicking o bubbling noise in the dash is one of two things that I have seen. It can be your ac servo motors or your coolant is low. The servo motors will click intermittently any time the key is on. The air in the heater core will bubble when the car is started or reved.

i think i have the same noise. i only notice it when i put it in drive and take off. it seems it does not do it while it is in neutral while reving. anyone talking about the same thing? it almost sounds like something wrapped around the drive shaft like a string to me.

if ur hearing a bubbling noise coming from behind the dash is that u have air in ur coolant system and that the car is low on coolant. u will need to bleed ur coolant system..if u heard clicking coming from behind ur dash that will be 1 of 3 of the servos that the car carrys 2 on the passsenger side and 1 on the drivers..if u start to hear the clicking u will most like hear it better if u stick ur head under the dash where u put ur feet..
