    Q:
    How to replace the front Seat Heater Pad on GMC Sierra 1500? Posted by Customer
    A:
    The process to replace the front seat cushion heater element begins with the removal of seat trim panel and seat cushion trim cover. You should disconnect the seat cushion heater wiring harness after you peel off its pad from behind the seat cushion. The repair process of the seat foam should be done with caution to prevent personal injury because any foam damage requires replacement of the inflatable restraint passenger presence system. You should begin by uniting the seat cushion heater wiring harness then you should add the seat cushion heater after which you should reinstall both the seat cushion trim cover and seat trim panel. Complete re-zeroing operations for the inflatable restraint passenger presence system on the front passenger seat by following correct procedures.
