The front seat memory switch assembly requires its retaining clips to be released for extraction of the switch before finally removing the assembly. Instillation requires pushing the front seat memory switch assembly into the front trim panel until complete seating then connecting the electrical connector before installing the front trim panel.

    How to replace the power seat switch on Chevrolet Impala? Posted by Customer
    A:
    The process of replacing the power seat switch begins with removal of the front seat cushion outer trim panel.
