It seems that there are two possible windshield wiper motors available for my car - depending on the particular VIN # that I have. One motor is $140. The one I need (apparently) is $300. Does anyone know what the difference is between these motors?

For VIN#'s ending in A644281 (or below), you can use the $130 motor.
For VIN#'s ending in A644282 (or above), you need the $300 one.

Any ideas are appreciated. Thanks, Jim.
