A buzzing noise at idle that increases with acceleration on a 1995 Chevy 4x4 pickup could be caused by several issues. One common source is a worn or damaged serpentine belt, which can create a buzzing or whining sound as it slips or vibrates. Another possibility is a failing component in the engine, such as a loose heat shield, exhaust leak, or a failing bearing in the alternator or power steering pump. It's advisable to inspect these components to diagnose the issue accurately.

That is the electric fuel pump that's inside of the fuel tank. That is a common problem with the Chevy trucks. A dirty fuel filter will cause the pump to make that noise or the fuel pump is wearing out.
yes, the fan bearing is worn out

Both bees and mosquitoes make the buzzing noises with their wings. Their wings are moving at such a high rate of speed that it makes the vibrations and buzzing sounds.
Because their wings move so fast that it creates a buzzing noise
Sorry forget to mention it in the motor.
Well, this is certainly among the strangest questions I've seen here. Is the buzzing from the headlight it's self, or is the noise inside the cabin?
