I turn on the heat and I get a squealing sound on the passenger side sounds like by the floor mats.
Also, when I turn the air completely off I get a golf ball rattling sound near the end of the power down just for a second

Anyone know what these two issues might be?
What kind of cost is involved?
Since its winter and my heat will always be on, I'll always have this squeal so I gotta fix it

Thanks car forum !

Check your blower motor

might be some trash in your blower.

To elaborate it is usually 3 bolts or screws holding it in. Put your head up in there and check it out.

just turn the music up like a pleb.

that'll fix it, right?
