Ford Focus Service Manual: Seat Cushion Heater Mat

Removal

NOTICE: Do not reinstall any heater mat after removal. The adhesive will not adhere correctly to the foam pad, causing it to bunch up or shift out of place. A new heater mat must be installed. Failure to follow these instructions can result in seat component damage and system failure.

1. NOTICE: Do not install a new heater mat on a front passenger seat cushion. If a new cushion heater mat is needed on the front passenger seat, an Occupant Classification System (OCS) system service kit equipped with a heater mat must be installed. Failure to follow this instruction may result in incorrect operation of the OCS system. For additional information, refer to Occupant Classification Sensor in Section  501-20B.

   Remove the seat cushion cover. For additional information, refer to Seat Cushion Cover — Front in this section.

1. Disconnect the cushion heater mat electrical connector.

1. NOTICE: Do not use a razor knife or other sharp tool to separate the heater mat from the foam pad. Damage to the foam pad may result. Install a new foam pad if torn or burned.

   NOTICE: If installing a new foam pad, the heater mat cannot be reused. A new heater mat must be installed. Failure to follow this instruction may result in component or system failure.

   NOTE:

   A new heater mat can be attached to the foam pad where the old heater mat was removed but a used heater mat should not be reattached to any foam pad.

   Carefully peel and remove the cushion heater mat from the seat cushion foam pad and discard.
   • If reusing the cushion foam pad, take precautions not to remove excess foam when peeling off the heater mat. If the foam pad is damaged, install a new foam pad and a new heater mat.

1. Inspect the cushion foam pad for damage. If damaged, remove the cushion foam pad from the cushion frame and discard.

Installation

1. If damaged, install a new cushion foam pad to the cushion frame.

1. NOTE:

   When adhering the heater mat to the foam pad, be sure to position the heater mat so it is straight and free of any wrinkles that may show through the material once the trim cover is reinstalled.
