Use Goodbye Spammer on silveradoZ71.
isolated sound, it looks like it's coming form under passenger glove box where black floor air vent is near center console. what's behind there?

I've pulled fuse on radio, amp, instrument cluster and it still starts buzzing noise when it hits that rpm range. I can put it in neutral to cause it. noticed it only starts when engine is at running temp. Sound like either in center of dash or passenger glove box area. checked tranny dipstick and i have insulation sleeve on it as well.

I had the same problem with my 2012 Silverado. Dealer disconnected the belt and noise was gone. Alternator....no. Idler...no. Water pump....yes. The noise from the water pump was coming through the heater core from 1,000 to 2,000 RPM. New water pump under warranty and all is quiet again. Unbelivable....but true.
