Hey folks,

I have a 2021 Wrangler JL that has a pretty annoying whistle when the heat is set to fan setting 5. Dealer has replaced the blower motor which did not solve the problem. No noise when AC is on, and I've distilled the location to the center of the vehicle. I took the glove box out and it's clear the noise is not originating from the cabin air filter area.

Does anyone else experience this? Ideas for solution?
