I Have A 2001 Grand Am Gt... The Blower Only Works On Fan Settings Of 3, 4, And 5... I Have Been Told It Is The Blower Switch Is This Possible Or Is There Something Else I Can Check First? If It Is The Blower Switch Where Is It Located?

I have a 97 Grand Prix with the exact same problem. No resolution yet. This happened after the radio display quit working.
Hopefully someone will have some suggestions
