a/c - dash center vent wheel noise?
 

i notice on my 2003 x5 4.6 , when i turn the a/c the dash center vent ,behind it i hear like a wheel noise,it does off and on,when it does that noise ,if i turn the a/c off it stops!,

is it something i need to change ?

anyone had this problem? before ? how you fixed it ?

thank you,

There is a fan inside the HVAC control that sucks air into those little vents on the face. This is to measure the interior air temperature. There should be a thread on here for removing the control unit then removing and cleaning the fans. I think the fans are also replaceable if cleaning doesn't fix it.

It's called the sampler fan.

hi,

and thank you to all for the info provided!

any chance you know the part number of that in case if i need to replace it?

will research it also,


thank you!
regards.
