Hello, I currently have three different noises that come from behind my dashboard.

1- rapid clicking noise, my guess is the AC servo.

2- Loud clicking that happens occasionally, it only happens sometimes and the clicks are always at least a second apart. It sounds like someone is flicking the dashboard if that makes any sense

3- faint squeaking noise when car is on. Sounds like mice but I really hope it isn’t.

Does anyone have any knowledge of these?

 

Look at the DIY for the servos.

 

It's the servo had mine replaced by and independent, AC shop I think I paid around $385.00 both labor and the both the servos. Now the system works great.

 

I rebuilt both of mine 9 years ago, which fixed the problem you describe...they still work great, no cost to me.

 

If you have any DIY skills you can spend about 3 hours and save hundreds!!!

 

I had this problem about 4 years ago and solved it by replacing Lexus Part Nos. 87106-30371and 87106-48020. I got a Toyota dealer to agree to a flat fee of 1.5 hours for replacing them. He later told me that I got a good deal, because it took him longer than that due to tight congestion in the dash.
