Remove the cover around the seat control switch using a screwdriver.
Disconnect the electrical connector from the back of the switch.
Use a multimeter to test continuity across the switch terminals. Replace the switch if it fails the test.

4. Inspect Electrical Connections

Tools Required: Basic hand tools
Move the front seats to their furthest position to access the connectors underneath.
Disconnect and inspect the connectors for any signs of damage or corrosion.
Clean the connectors with electrical contact cleaner and reconnect securely.

5. Replace Heating Elements (if necessary)
