Wiper Motor Code.........

Was wondering if there is anywhere I could look up codes, for different components of a car. I would like to know for myself when these parts were made for my car and have it recorded for my records. Example, I have a heater blower motor that I'm about to restore and there are two lines of numbers on it. What do they represent. First line is 362 837, and the second line is 42166 0643. Can anyone help me out on this. Help would be much appreciated. Thanks ED...
