I need some help? I have a 2005 Subaru Outback Turbo, and I am somewhat car savvy, but I am stumped. This car has about 160k miles on it and it has a high pitched sound from the heater fan. It actually lowers in pitch as the fan increases in speed. At high speed you almost cant hear the sound.
Now I have tried replacing the fan, but that did not help. I have removed the fan wires to make sure the sound is coming from the fan, and with the fan disconnected the sounds goes away (of course the fan doesn’t work with the wires off). I really don’t know what could be causing this sound.
I know Frank and Ray would say to turn up the radio, or leave the fan off, and I have tried both, but eventually I would like to see if there is a real fix.
Anyone have an idea??
