I have a 2015 TC. I changed out the cabin filter about month ago because the blower fan was making a lot of noise on 3 or 4. When I took the old filter out, it was ripped to shreds and it took a long time to clean out all of the debris (mostly insulation) from the fan and filter slot. I installed a new carbon filter. Recently the noise started up again, so I pulled out the new filter (which was still intact) and again found lots of debris, this time mostly plastic with a little bit of insulation (pic attached). It's like the fan is sucking in and shredding insulation from somewhere? Anyone ever heard of or experienced a problem like this before?
