Air outlet control servo motor

[Madartsoft]

Hi,

I just noticed that when switch off the AC and blower I can hear noise such some mechanism moving randomly up and down trying to find position. I read that it could be Air outlet control servo motor. I checked error codes and it shows no error but sound still exists. I found the servo which cause the strange sound. It's located under the dash I can even touch it by hand. I wonder if someone replaced this servo or fixed? How to remove the servo as it's not under the glove box (better access I think). It's driver side.

The sound appears when I switch the fan mode it's not related to the fan speed or temp.

This appears to be a fairly common problem, certainly on the US forums.  One issue is the worm gear in the servo works loose.

Is the servo making a noise continuously?

Hopefully this search works for you; https://www.google.co.uk/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=lexus+rx+servo+site:www.clublexus.com&safe=on

If I set the air flow (foot or front and foot) then the servo making noise continuously, in other positions it's ok.

Thank you for the link but in US models the glove box is on the right side which make simpler access to the servo but in UK car models there is a steering wheel and I guess it's much more complicated to get there.

Do you know that your RHD vehicle will be anymore difficult to fix?  The steering wheel might actually make the job easier on a right hooker?

After a another quick search it seems a relatively straight forward job to do on a RHD car, link below.

I took a look at the servo's in my GS for the passenger foot well receiving only cold air and that was a royal PITA. Some bright spark decided to mount 2 servo's on a mounting plate that then hooks up to 6(ish, I'm trying to forget it was soooo awful) mostly independent pins, slots/guides.  Trying to get everything lined up was a complete pig.  It's looks like you just have 1 servo to work on, so I reckon it'll be much easier for you, so get crackin'...

Thanks for reply. Disconnecting air bags doesn't sounds good but it's better than visit Lexus.

Is there any place where I can buy brand new Lexus parts except Lexus dealer?
