    The encoder motor moves the shift fork. If it were messed up you'd get codes and a message.

    New problem

    Make sure the switch is plugged in.

    Make sure the fuses in all three locations are good. Make sure the module is plugged in and you do not have a windshield leak getting the module wet.

    Beyond that you need scanned for codes.

    You also need to make an introduction topic in the newbie section.
