I drive a 1997 Chevy Suburban and the Heat only works on high and makes a really loud noise that sounds like a garbage disposal? The rear heat works fine. I was Wondering what it might be and how much would something like that cost to fix? Thank you

The fan only works on high because your blower motor resistor is bad and it makes that noise because the motor bearings and/or fan blade hub are worn out. If you replace the motor it doesn't usually automatically come with a fan blade. These parts are available aftermarket and aren't very expensive. The motor goes in under the glovebox
