DESCRIPTION

Some customers may complain that the seat warmer does not operate when turning the ignition on while the seat is warm but when turning the ignition off then on again, the seat warmer begins to operate appropriately. DTCs "B1030:13" and/or "B1032:13" are stored. This is caused by the seat warmers fail-safe mode which prevents it from working during the initial drive cycle. To correct this issue, the seat warmer has been modified to optimize the temperature control.

Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE

  1. Verify the customer concern.
  2. Remove the front seat cushion trim and the front seat back trim for both the driver and passenger seats according to the instructions in MGSS.
