Heated Seats

WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If a passenger seat cushion heater mat is inoperative, a new Occupant Classification Sensor (OCS) system service kit must be installed and a new cushion heater mat must be installed to the OCS system service kit foam pad.

NOTE: When installing an OCS system service kit equipped with heated seats, a new seat cushion heater mat must be installed. Do not reuse the OEM OCS cushion heater mat. The OCS system service kit does not come with a cushion heater mat.

NOTE: When installing a new driver seat heater mat (cushion or backrest) or passenger seat backrest heater mat, a new foam pad with the heater mat already attached is required. A new seat heater mat by itself is not available for service for the driver seat.

Vehicles with front heated seats are equipped with a heated seat module which controls both front heated seats. The heated seat module is located behind the front passenger door trim panel.

Vehicles with rear heated seats are equipped with 2 rear heated seat modules, one for each LH and RH seating position. Rear heated seat modules are located behind the rear seat backrest behind the LH and RH seat positions.

Front and rear heated seat system operation is similar. The system only operates with the engine running. When the heated seat switch is pressed a momentary voltage signal is sent to the heated seat module. The heated seat module then supplies voltage to the heater circuit. The cushion heater mat and backrest heater mat are wired in series. When the system is on, the heated seat module supplies ground to the heated seat switch to illuminate the indicator. Rear heated seats turn off after 10 minutes. Front heated seats do not time-out. The heated seat modules monitor temperature sensors in the cushion heater mats and regulate the outputs to the heater mats to maintain seat temperature until switched off or a time-out occurs (rear only).
