Hello everyone I did a search and tried almost everything, but it seems the humming just won't go away! When I accelerate it makes a high pitched humming noise. So what I've tried was checking my power steering fluid, which was low, I filled it up but still the humming persists. Also, I tried having my car running switched to natural and turned off my car and there was no noise. So that eliminated the drive train. Also I am not exactly sure where the humming sound is coming from. Oh and when I row up my windows all the way and then row them up more it makes the humming noise, but it isn't coming from the window motors. I am really stuck any suggests or help is greatly appreciated. Thank you for you time and I hope to hear back from you guys soon!
