I get lots of periodic Buzzing noise through the Bose Radio. It happens randomly. When it happens blinker noise and brake peddle will add noise.
Starts with a closing of a door our a bump in the road.
Any Idea's where to start?
I had the same thing happen in my Yukon, anyway too make a long story short I found that the amplifier had a bad ground, so I fixed the stock ground and added another ground wire to the case, no more whine.
Where is the Amp Located?
Mine was behind the glove box. I don't really know where yours would be. Could be in the same spot.
