Front Seat Heating Elements Inoperative
AFFECTED VEHICLE RANGE:
Discovery Series II (LT)
XA 900000 to XA 907212
XA 200616 to 1A 299999
1A 700000 to 3A 799999
3A 800000 to 3A 824321
SITUATION:
SEAT HEATER PAD DAMAGE
Compression of the seat cushion during entry and exit from the vehicle causes the seat heat pad on the cushion to 'flex.' Damage to the element wire
strands can result. The current through the element remains constant which can cause localized hot spots within the element where the wire is damaged.
RESOLUTION:
REPLACE FAULTY HEATER ELEMENTS WITH NEW PAIR
Should a customer complain about localized hot spots on a seat, the seat cushion element must be replaced. Due to the changes introduced to the latest
seat cushion element replacement components the seat squab (backrest) element must also be replaced at the same time as the seat cushion element to
ensure that the resistance between both elements remains balanced. The dual replacement conditions only applies on vehicles up to VIN 3A 824321.
