Component Tests and General Diagnostics

DIAGNOSIS AND TESTING - HEATED SEATS

Before testing the individual components of the Heated Seat System, ensure the battery is fully charged, then check the following:

- If the Heated Seat Switch LED indicators do not illuminate with the Ignition Switch in the ACC or ON/RUN position and the switch pressed, check Fuse 1 and Fuse 24 in the Underhood Accessory Fuse Block. If OK, see Heated Seat Electrical Diagnostics. Electrical Diagrams. If not OK, repair the shorted circuit or component as required and replace the fuse.
- If the Heated Seat Switch LED indicators illuminate but the heating elements do not heat, inspect the heated seat system harness connections for looseness or corrosion. Clean and tighten all the connections to ensure proper circuit continuity and ground paths as necessary, then retest the system. For complete heated seat diagnosis, see Heated Seat Diagnostics. Electrical Diagrams.

NOTE: The Heated Seat System utilizes a unique low voltage cut-off feature. This feature deactivates the power seat system anytime the available system voltage is below 11 volts. Be certain to check the vehicle electrical system for proper operation anytime the heated seat system appears inoperable.
