Anyway to work out which fan is squealing??

I have crickets in my X which seem closer related to the blower fan, but can't be confident!!

Anyone able to help me out??

The sampler fan DIY is simple, would start there. If it turns out the be the blower motor it would not hurt to clean/lube the sampler.

I suppose with my X5, equipped as it is with the manual IHKR controls...

... a squeak when the blower is running means tearing the dashboard apart. :(

Interesting that the cars with the IHKA HVAC controls have a fan specific to sampling air; the IHKR cars have a vacuum hose routed into the cabin that pulls air into a sensor under the dash near the driver's door, just like the older cars.

Mine squeaked for two years whenever it got cold outside. Now it doesn't anymore. No changes. No fixes. Just no noise.

Probably because it finally broke. Just like the black tape that people put over a CEL so they don't need to look at it.

Meant as a joke? I can't tell. But no, it is not broken. Still performs well and heats the car as it always did.

Why it suddenly stopped squealing, I can't say. But like my panoramic roof that was jammed for about six months then started working again, I really dont care too much why, just glad it does.

Mine has been squeaking for the past 6 months...hope that it's not the beginning of a new blower motor replacement :(
