Just bought an 85 monte carlo ss. When its off I hear a buzzing or squeeling sound coming from the driver side dash. Opened the hood and I cannot hear it, just from the dash and it never stops. Anybody know what this might be?

Thank you

 

I also have a 1985 Monte Carlo SS and had a squealing noise coming from the passenger side. It drove me crazy until I realized that the visor was rubbing and making the noise.
