I notice yesterday for the first time an intermittent humming while driving. It's not dependent on accelerating, coasting, braking, AC on/off, fuel tank selector....but it didn't do it when stopped. It also didn't do it while accelerating up a steep hill.


It would also come and go for maybe 5-10 seconds at a time with silence in between. I have no working radio so I was listening to try to find a pattern to it and I couldn't. It seemed to be most audible from the drivers side of the dash near the vent or left side of the dash
