hi,i started to hear aclicking sound coming from the engine toward the dash,not a dash rattle,i tried putting off the AC and Fan but still there, i can hear it with engine run.any ideas please.

 

Is it more like a faint ticking sound when the engine is idle?
Is the sound faster if you push the pedal slightly?
Is it more noticeable in cold weather?

 

yes to all,please tell me if you are aware of the problem or the solution..thanks

 

>>>>please tell me if you are aware of the problem

Yes - I'm aware of the noise. I've been told my my tech advisor its noisy fuel injectors, so its not really a "problem"....but a nusance (like the dash ticking or the tranny clunk which have both been fixed).

Call Lexus and voice your feedback. If enough people call it a "problem", they'll get around to addressing it. It bothers me, my wife doesn't hear it.

For what its worth...In the summer, it was non-existant on my RX. But as the weather gets colder, I'm starting to hear it again although it seems quieter than before...

>>...or the solution

Play a nice CD while we wait to hear from Lexus :-)

 

or play a cd to overpass the sound! lol better than my problem in where every time i release the brakes, i experience my thump problem! (can't overpass that with a cd )

 

There are 2 servos that have to do with the A/C they are behind the dash one or both have to be replaced. Take it to the dealer have it diagnosed so the can find which servo is acting up. Replaced one earlier this week, it was one that was behind the glove compartment area. LEXus + TECHnician = LEXTECH = me

 

(Not Lexus Technician = blue_rx330)

Aren't servos only for small controlled movements rather than constant rotational motion?

If I'm reading the post correctly, the problem shikbas describes is a constant sound rather than an occassional sound (like when the AC kicks on or off, or the AC shifts from floor vents to front vents, etc...). And the his sound exists with the AC off and the Fan off.

If the clicking was only when something changed, then its probably servo related. But if its a constant noise, I would think it would be something like a fan motor, belt, or (as my dealership diagnosed), noisy fuel-injectors.

Does that make sense, or am I totally off base?

 

ive been told its the injectors as well. oh well. nothing is absolutely perfect.

 

thank you all for the answers,i am very pleased with such a nice people.Do you think there is a fix

 

I guess I didn't say that when the servo(s) go go bad they could begin to twitch contantly whether or not the A/C is on

 

i meant "go" not "go go"

 

I'm reffering to RX300's not 330's

 

I just got my RX300 back today from the dealer. One of the things they fixed was my clicking noise for the glove box. With the car running and in park. With the stereo and A/C off. You would hear a clicking noise. And a running noise. The best way I can descricbe the running noise. Is the noise a hamster makes while on the wheel in their cage. It would speed up. And then slow down. They replaced the Servo S.A. Damper.

LEXTECH had a question. Do you have to take the dash off to change these?

 

How much did they charge for the Servo S.A. Damper?

 

My 2001 is a Certified Pre owned. And its still under 50K miles so it was all warranty work.
