Driver's cooling fan vibration and loud noise

[2019silverado]

2019 Silverado 1500 High Country, the other day I turned the cooling seats on and the fan in the back of the drivers seat made a continuous loud noise and hard vibration.  Has anyone else had this happen?

Looks like the fan is more or less sealed inside the seat back leather.  I'm wondering if I bring this in to the dealer, how they will tackle it.

No, mine has been fine.  They will remove the leather seat cover.

Mine has done that on the drivers side when its cold. I accidentally turned on the air instead of the heat and it made that noise. If the temperature is warm it wont do it.  Hope this helps.

My passenger seat does this.  Sounds like crickets.  More cheap foreign parts with bad bearings?

Yup.  Under warranty and completely unacceptable.  Got an appointment in 3 days to fix/replace it.

Yup I started a thread myself on this issue. Not many replies over there. but yes I have the same issue. I have noticed this and its random but does seem to happen when its been cold. Please keep us updated about what they say.

Same issue here started a week or so ago when I turned it on on a cold day. Seems to go away after about 30 seconds but definitely not what you want to hear right behind your head.

Ok.  I took it to the dealer for the fan noise/vibration issue and on the work order it stated that there was seat foam in the fan itself causing the noise etc.  Removed the fan and removed the foam and reinstalled the fan and all is good now.

Well, the noise and vibration is in fact worse now so I took it back to the dealer and they said they ordered a new fan for it so I'll keep you posted on how that turns out.

 

Just wondering, does anyone know for sure how they get to that fan in the seat back?  1st work order stated they removed and cleaned it and then reinstalled it.  How?  I didn't see any indication that anyone got into the seat.  I wish there was a schematic of the seat somewhere so I can visualize this.  I've searched, got one microscopic rough drawn picture that you can barely see.

I did the exact same thing the other day and had the exact same results.  FYI the fan was dead quiet last time i used it in warmer weather.

Update:

Had the new fan installed yesterday and nice and quiet now.
