Since the onset of the frigid temperatues, my Integra has been having a rattle in the dashboard. I beleive it to be something with the speedometer, as it is at its worst when the car is cold. As the car warms up it becomes softer. It also stops when im not moving. The speedometer seems to work fine other than the rattle when cold. Is there anything I can do to alleviate this, aside from replacing the speedometer?
