Fan noise from behind dash?
Guys I have a fan noise that goes with the Rev range sounding behind my dash in the middle any ideas? I can stop it by turning off my a/c which currently isn’t running due to outside temps of 2C so it’s not a/c related
Help pls Thanks |

No, what I meant: If you have the A/C off and just the fan on and play little with the speed...then anything to hear from the frequency of the noise?
I ask because sometimes the fan soaks some foreign objects against the grilles under the bonnet and sometimes those objects made it through until their get ripped to shreds...but until this finally happens, they're making disturbing noises.

How old is your car? Maybe the blowby heater itself with a beginning electric motor failure?

whirring noise
Guys has anyone seen this as the culprit to the noise? think the engine is petrol but could still have the same issues on diesels too.
This is from BMW America. https://static.nhtsa.gov/odi/tsbs/20...47979-9999.pdf Jody. |
