Buzz Coming From Digital Dash

Here are the basics -
88 Cougar w/5.0 (HO) loaded w/digital dash

I have started getting a buzz coming from behind the dash.  It becomes audible at around 35mph and increases in intensity as the speed increases.

It is not the radio.
It is not a vibration.
It has the sound of electrical arcing.
It sounds like it is just on the other side of the digital dash.

Two problems that I have recently had are the cruise control and the low oil lamp.  The low oil lamp I believe to be a relay as the switch and the oil level are fine. The cruise began acting up then just quit.  I mention these here in case ther might be some relation between the buzz and these two items.

Any ideas?

Are your wipers in the fully parked position? Try turning them on and off to see if the noise changes
