Fixing Non-Working Heated Seats in a 2020 Chevrolet Silverado 1500

Tools Required
  • Multimeter
  • OBD-II Scanner
  • Flathead and Phillips screwdrivers
  • Torx driver set
  • Pliers
  • Replacement fuse (if needed)
  • Replacement seat heater switch (if needed)
  • Wiring repair kit (if needed)
Repair Instructions
Step 1: Check and Replace Fuse
  1. Locate the Fuse Box:
    • Open the driver's side door and remove the cover from the fuse box.
  2. Identify the Correct Fuse:
    • Refer to the diagram on the fuse box cover to locate the heated seat fuse.
  3. Remove the Fuse:
    • Use fuse pullers or pliers to gently pull out the fuse.
  4. Check the Fuse:
    • Inspect for a broken filament. If the fuse is blown, replace it with a new fuse of the same amperage.
  5. Test the Heated Seats:
    • Turn on the heated seats to see if they are functioning.
Step 2: Inspect the Heated Seat Switch
  1. Access the Switch:
    • If the seats are not heating, you may need to remove the switch from the center console.
  2. Testing the Switch:
    • Use a multimeter to check for continuity. If no continuity is found, replace the switch.
  3. Replace the Switch:
    • Disconnect the wiring harness from the old switch, install the new switch, and reconnect the harness.
Step 3: Check Power to the Seat Heater
  1. Remove the Seat:
    • If necessary, remove the seat to access the connectors beneath.
  2. Test Connector Voltage:
    • With the multimeter, check for voltage at the seat heater connector while pressing the switch.
  3. Repair if Necessary:
    • If no voltage is present, trace back the wiring to find the fault.
Step 4: Inspect Wiring and Connectors
  1. Visual Inspection:
    • Check the wiring harness for any visible signs of wear, damage, or disconnection.
  2. Repair Damaged Wiring:
    • Use a wiring repair kit to splice in any new wire if necessary. Ensure all connections are secure.
Step 5: Scan for DTCs
  1. Connect OBD-II Scanner:
    • Plug the scanner into the OBD-II port under the dashboard.
  2. Read Codes:
    • Follow the scanner instructions to read any stored DTCs that may relate to the heated seats.
  3. Resolve Any Issues:
    • Address any issues indicated by the codes, which may guide further troubleshooting.
Final Check
  • After performing all the steps, reassemble any components removed during the process.
  • Test the heated seats again to confirm proper operation.
Conclusion

If the heated seats still do not work after these steps, it may be necessary to consult a professional technician or visit a dealership, as the issue might be more complex, involving the vehicle's body control module or other integrated systems.
