Re: 12 Jeep GC High pitch humming noise from Gauges?!
I originally clicked on this thread because I thought it was related to what I hear. However, it sounds like it's different.
What I hear is when the vehicle is turned off.
It sounds like a very faint electronic noise like some sort of robot cricket chirping away. My guess, it's some sort of feedback from either the alarm system or the proximity detection for the key fob. I hear the same noise with my wireless Qi charger for my phone.
What I assume is, it's in low power mode at that point and using some kind of pulse to ping out at a regular interval, about once a second.
It's very faint, so many people might not even hear it since it's also somewhat high pitched, much like the whine that older tube TVs always made when turned on.
I don't think it's any sort of problem, but I'd be interested to know what is actually making the sound.
