I know it is a silly question. For the life of me, I can't figure out how to find the build date on my 2012 Routan. Thank you.
There are no silly questions, only silly answers, so, here's the silly answer : The build date can be found on the white label on the rear inside edge of the driver's door [just look down as you open the door].
It gives you the month and year of manufacture, but not the day. Mine, for example, says 11-08, so it's a 2009 model built in November of '08.
If the Routan label is like the Chrysler/Dodge labels then there should also be a MDH field followed by a 6 digit code, this code is the two-digit Month, two-digit Day and two-digit Hour (in 24-hour format) that the vehicle was manufactured.
My Caravan label has the following information:
Date of MFG: 12-08
So my van was built on December 18, 2008 at 1500 hours (3 pm).
