Tapping in the dash
 

When I'm running my car a lot of times at startup I hear this light tapping in the middle of the dash above the center vents
Everything functions fine but I have no clue as to what it could be?
Any ideas?
Thanks everyone

Air conditioning servo motor going out.

It doesn't do it when the air's on bruceb58
It does it when I start the car

Trust him, it's the servo motors.

Read this thread, it'll show you what parts to get and how to fix it yourself: https://www.clublexus.com/forums/gs-...vo-motors.html

There's 3 of them, but you won't have to replace all 3 of you don't want to. Someone correct me if I'm wrong, but I believe there is a servo that controls the temperature on the driver side, another servo that controls the temperature on the passenger side, and a servo that controls the mode (when you switch from face/feet/both/windshield/etc). Driver side servo is on the... driver side! Passenger and Mode servos are on the passenger side.

I've already used this to fix my driver side. I think my mode servo is going out because I get some clicking every once in awhile from the center of the dash. I won't be fixing that unless it gets really bad because I rarely switch modes. I keep it on face all the time.

Was my mode servo. Did it when I started up the car and various times during the day.

there are 4 servos actually.... 3 on the passenger side and 1 on the drivers

Product #:8710630371 Lexus OEM Damper (For Mode) Servo Sub-Assembly

Product #:8710630341, Lexus OEM Damper (For Cooling Unit) Servo Sub-Assy

and then a air re-circulation servo on the passenger side and then 1 more servo on the drivers side (different part #)

Thanks Everyone
I appreciate all the info & will get on this soon
