I did a quick search and browsed the TSBs and came up with nothing. The noise sounds like it is coming from the within the dashboard (or at the firewall) on the driver's side -- it sounds like a grind, like a child's wind-up toy would make. This noise only occures for a second or two and only happens when the temperature is below 40 degrees F (only happens on initial startup). Also, I noticed that the noise occurs before the tach begins to read engine RPM. Any clues as to what the problem(s), if any, are appreciated.
