davgrooms Posted June 19, 2005 Posted June 19, 2005 I think I have come to the right place. I have a strange, irregular clicking noise coming from under my glovebox on the underside of the dash, directly below the cd-changer. I initially thought it was the changer, but on further inspection, I realized that it is actually below the glovebox. When I place my hand on it, I can actually feel the moving. I also thought it might be a critter of some sort, but it has persisted for several weeks now. It occurs once the car has electrical (when I turn the key to power on) It remains even when the engine, A/C, and stereo are all off. It definately sounds mechanical, but I have no idea what is located there. Does anyone have any ideas, your help is greatly appreciated. Thanks alot
davgrooms Posted June 19, 2005 Author Posted June 19, 2005 I took apart half my car this morning, and I believe it is the air conditioning air inlet servomotor. I located it twitching, so I assume the problem is with the servo itself and not with the control. does anyone know a good place to get a decent price on lexus parts? -Thanks
pushatam Posted June 20, 2005 Posted June 20, 2005 i got the same thing going on! it sounds like my car is making popcorn i also have a warrenty. anyone know if this is a real problem besides its audible annoyance?
pushatam Posted July 7, 2005 Posted July 7, 2005 does anyone know if this would be covered under lexus' powertrain warrenty that covers 2001s with under 70k miles?
stonecutter Posted July 7, 2005 Posted July 7, 2005 does anyone know if this would be covered under lexus' powertrain warrenty that covers 2001s with under 70k miles? ← you wouldn't know till you try to make a claim, but i doubt it.
soggy60 Posted July 14, 2005 Posted July 14, 2005 [Took our 2004 RX 330 to dealer Monday evening.... they said 'should be ready toimorrow' . . . well, a/o this afternoon...."next week" . . .parts shortage At least we've got a nice 2005 ES300 loaner . . . Oh my, the 330's been such a let down . . . After the 1990 LS400, an RX 300, LX470 . . .this 330 ain't up to par . . .
soggy60 Posted July 19, 2005 Posted July 19, 2005 Well, here we are a week later and A/C still not fixed....still waiting on parts for that clicking noise behind glove box . . .
Rx330driver Posted July 19, 2005 Posted July 19, 2005 hmm, i have never heard any clicking sound below or near hte globe box. the only problem with sound with my rx330 is the clicking during high speeds in the drivers window. gah, that was a problem in the rx300 and it still bothers me
soggy60 Posted July 29, 2005 Posted July 29, 2005 Finally got 'er back . . . They (Lexus dealer) managed to find part & replace . . . In July 11 Out July 28 No more little 'clickety' noise . . . Now, if they could just do something about the engine-tranny no response situation . . .( like the rig doesn't respond when pressing accelerator...)

soggy60 Posted August 1, 2005 Posted August 1, 2005 Was it covered under warrenty? the powertrain warrenty? ← Yes,,, Quite innocently, the young lady at 'pay for service' area, stated "They'll be no charge for todays service"... The humor: " today's service "
Booyah Posted August 2, 2005 Posted August 2, 2005 Now, if they could just do something about the engine-tranny no response situation . . .( like the rig doesn't respond when pressing accelerator...) ← Have you got the latest reflash? A new one has just come out about a month ago and it did make a nice differance I thought..... Its the same TSB as the older one on this issue they just revised the update with New software for ya....

pushatam Posted August 2, 2005 Posted August 2, 2005 Was it covered under warrenty? the powertrain warrenty? ← Yes,,, Quite innocently, the young lady at 'pay for service' area, stated "They'll be no charge for todays service"... The humor: " today's service " ← thats so awesome they fixed your rx. I am pretty sure I have the same exact problem as you. the clicking is a total nuisance. What should I tell the dealership when I go get it fixed? I am not really interested in paying them just to find out what the problem is. also, why was it fixed for free ?
chubyball Posted August 2, 2005 Posted August 2, 2005 I have a LS400 95s, got same noise and found out that the cabin filter causes that noise.

The humor: " today's service " ← .... also, why was it fixed for free ? ← Warranty ? Rig is about a year old (2004), not too many miles, we're the orig owner, We Wouldn't Pay Any Way ! Rig's been in shop way too much for BS items... ( tranny issues, see other threads; body panel / wind noise, etc) As for the adjacent post about '. . . filter causing noise...' If you get the noise that I, and others, talk about, you'll know it. Although not real loud, it's a very repetative mechanical type of noise; independant of vehicle speed or A/C setting. "Sounds like" a servo system hunting . . .almost the sound of cycling the passanger chair forward and back and fore and ....but sound definately from under/behind glove box.
GoldenStateSilverSport Posted August 25, 2005 Posted August 25, 2005 Unfortunately, I hvae the same issue in my 01 RX300 Silversport...the annoying sound keeps clicking from under/around the CD/glove compartment area. Don't know if I should take it in or not ..my car has about 56K miles...and i got my car in June 01 so i think the warranty is up.. :(
Rollingstone Posted August 30, 2005 Posted August 30, 2005 I too have the anoying 'clicking' sound near the glovebox. You'd think someone out there would post a 'fix'. I just turn up the great stereo and count my blessings that it's not the Lexus Service Dept cash register that's doing the ticking. I just spent over 6 grand replacing the transmission - enough is enough!
dcfish Posted August 30, 2005 Posted August 30, 2005 I have a LS400 95s, got same noise and found out that the cabin filter causes that noise. ← This was in another forum-The noise is coming from the servo motor that moves the door for the "mode" button. This servo moves diverters to change from vent to floor, etc. - I popped the bottom panel off under the glove box. - I then removed the glove box assembly. 2 screws up high, 2 bolts down low. - With the key on engine off you can press the mode button and watch the servo move. Turn the key completely off. - Remove 3 screws and plug to take the assembly out. - Do not attempt to rotate the arm on the end of the servo. It engages w/ a worm gear. Turn it and you will break gears. - The servo is a snap together unit. Carefully take it apart w/ the arm side down.(so gears don't fall out) - inside you will see multiple whiper fingers that make contact w/ a gear. Carefully clean these w/ alcohol and a cotton swab. - Redistribute the contact grease on the whiper pad w/ a clean finger (any oil or lotions on skin will mix w/ the grease and make the copper contacts corrode. - Carefully snap unit back together. - Clean contacts on the outer part of servo also w/ alcohal. The other option is to have Lexus diagnose this for you and hit you for $160 for the part plus ~ an hour or 2 labor. So far the noise is gone and the HVAC system works properly. I will post any updates if the problem comes back. I think the problem was caused by crusty contacts in the servo that were creating a poor signal back to the computer that controls it. Now that it has a clean signal, all is well..... I hope!!!
GoldenStateSilverSport Posted August 30, 2005 Posted August 30, 2005 thanks, DC fish...couple of questions.. What do you mean by "mode" button?.. is that a button on the Radio/AC dash? How hard is it to complete what you just mentioned? Sounds a bit challenging. I wouldn't say I am a pro, but I can do the regular stuff like change my oil, filters, and conduct minor services. thanks

That was done by someone else, Not me although I will be doing the procedure soon. Good Luck
dcfish Posted August 31, 2005 Posted August 31, 2005 The mode button switches where the air comes out. ← Thanx, I should have looked rather than guessed.
Rollingstone Posted August 31, 2005 Posted August 31, 2005 Thank you DCFish - now if only we could locate someone who knows why the tranny fails on the RX300 AWD. Oh well, one step at a time - Thanks again
IndyKen Posted September 4, 2005 Posted September 4, 2005 Way to call it, DCFISH!!! It worked exactly the way you described it. Thanks for the fix and saving me a couple hundred bucks!!
