Clicking Gurgling behind dash when outside temp rises
I have a '99 GS300. I have researched posts on here before but am not sure what I am looking for. I am assuming a servo motor but not sure which one. I get a clicking gurgling sound behind the dash. This only happens when the outside temperature is 70ish or above. It doesn't matter if AC is on or not or even if the motor is running.
Any advise appreciated.

Easy way to tell is to pull the glove box out completely, turn key on and wait. Once it starts clicking, you can put your hand on the servos and narrow down which it is. You should feel it clicking/vibrating. Low coolant will cause a very similar sound as well but mainly on acceleration as the water pump spools up putting more output to the heater system and the trapped air makes the gurgling sound as it passes through the heater core. I had a Z71 do this forever and I thought the AC drain was plugged up filling the box with water.....changed radiator and bang, noise was gone. Your problem is the servos though. They most likely need removed and greased. Again, search before new thread or you will get the negative responses. Hope this helps.
