Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box corresponding to the heated seats (refer to the owner’s manual).
Remove the heated seat fuse and inspect it for continuity using a multimeter.
If blown, replace it with a new fuse of the same amperage.

3. Examine the Heated Seat Switch

Remove the trim panel surrounding the heated seat switch using a trim removal tool.
Disconnect the wiring harness from the switch.
Test the switch for continuity with the multimeter. Replace if faulty.

4. Test Heated Seat Elements

Remove the seat cushion cover according to the service manual instructions.
Locate the heating elements and disconnect their connectors.
Use a multimeter to measure the resistance of the heating elements (should typically be around 1-2 ohms). Replace if out of specification.

5. Reconnect and Reassemble

Reconnect any wiring harnesses that were disconnected during the process.
Reassemble the seat cushion and trim panels securely.
Reconnect the negative battery terminal.
