When driving my 4.2l at speeds approx. 55 mph, I hear this strange repeatitive clicking sound coming from the lower left side of the dash. When I decrease speed, the clicking sounds stops. I would guess something in the fuse box but what? This isn't a dash rattle but something more like an electrical component.
Any advice please

 

WOW

Thats a new one.

A BOMB? and it you go over 85 MPH it will go off.

J/K

Is it anything like the problem DjThomasJ was having?
