I don't know if anyone else has had to McGuyver a solution to this, but I've got an '06 Cobalt with manual windows, and after replacing the front speakers the window handles both buzz or resonate from the sound, it's really irritating. Jamming a piece of paper or something else between the crank handle and the crank itself fixes it, but they always fall out given enough time. Has anyone found a safe, effective way to eliminate this buzzing?
