Luvmy, I did a cheap fix on my aspirator fan.
I took off the tiny grill, moved the temp probe wire to the side with needlenose pliars, and stuffed
some insulation down to the fan.
Got me through one cold winter without that grinding noise.
The permanent fix is what Submariner says ... replace the fan, because the bearing goes bad.
Good luck, enjoy your ride.
