A buzzing/vibrating sound just started behind or somewhere around the instrument panel on my 97 GLT wagon. I took the ABS module out to send to Victor Roche two or three weeks ago and did not notice it either before or while it was out. But as soon as I put it back that's when I first started hearing it. I've read about the little speedometer gear going and know the speedometer is tied to the module, but I'm not certain that it's some gear. The noise does not increase with speed, and sometimes seems connected to the roughness of the road, but not always, sometimes stopping for a few seconds, and then starting again, intermittent. Does this ring a bell with anyone? Dick
