I have this annoying whining/buzzing noise when I have my air blower on. I’ve isolated to the blower itself. Took it out and tested it and works fine. Checked for debris in compartment, cabin filter etc. Nothing. Once the blower is back in the compartment, noise starts. I figure it’s some sort of harmonic frequency that just happens. There is an electrical tape on the bottom of the blower, it covers the spindle. When you put your finger over it, the noise is muted. It seems the Impreza had this problem for a long time and Subaru created an insulator to cover the blower to mute the noise. Anyone having this problem and suggestions for a fix?
