I checked out the DIY, doesn't seem that bad but...
seems the cause is poor design and water getting in the housing and rusting the bearings up.
there is TSB from BMW but I cannot find out mroe info on it ... its "Water Ingress from A/C Blower Housing"
does anyone have this TSB or can let me know what it is refering to? Sounds like if the filter isn't sealer properly, water can get down inside the housing. Will BMW fix this under the TSB?
