Do Not Sell My Personal Information Jump to content

Recommended Posts

Since I bought my late 2013 is300h back in March 2019 I have always had this one noisy vent flap in the climate control system. It is usually quiet during summer but as temps fall it tends to get noisy. 

usually orchestrates itself:

-upon startup (I guess these flaps somehow block the vents when in parked position and they move back to their original position upon startup)

-when changing the temperature on the climate system

Does anyone else have the same issue and is there a fix? Thought about removing the vent flap actuator and giving it a clean but it sounds like it’s the actual flap making the noise (plastic/rubber on plastic noise)

is this the noise you can hear, if it is i had a new ventillation system fitted under warranty


Yessir that’s it exactly! Unfortunately way out of warranty but will live with it then. If I ever do find a solution I’ll report back

i believe it was one of the distribution flap pivot points

that was worn and caused the noise
