  1. If a single LED indicator lamp for one heated seat switch/module does not operate and the heated rear seat elements heat, replace the switch with the inoperative indicator lamp. See REMOVAL .
  2. If both LED indicator lamps for a heated seat switch/module operate, but the heated rear seat elements do not heat, see DIAGNOSIS AND TESTING  to check the suspect heated rear seat elements. If the elements test OK, proceed to check the suspect heated rear seat elements. If the elements test OK, proceed to step  1.
  3. If both rear seats fail to heat and the indicator lamps on the heated seat switch/modules for both seats fail to operate, test the heated rear seat fuses in the Integrated Power Module (IPM). If the heated rear seat fuses check OK, go to step  1.
