how to fix the heated seats not working in my Volkswagen Golf MK7 (2015-2019)

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, screwdriver set, socket set, trim removal tool
• Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Fuse Inspection

• Locate the fuse box (usually found under the dashboard or in the engine compartment).
• Remove the cover and identify the fuse related to the heated seats (refer to the owner's manual).
• Inspect the fuse; replace it if it is blown using a fuse of the same amperage.

3. Wiring Inspection

• Remove the seat from the vehicle using the socket set to unbolt the seat.
• Disconnect the wiring harness from the seat.
• Visually inspect the wiring for any signs of wear, fraying, or disconnection.
• Repair or replace any damaged wiring as necessary.

4. Seat Heater Element Testing

• With the multimeter, set it to measure resistance (ohms).
• Disconnect the seat heater element connectors.
• Place the multimeter probes on the terminals of the heating element.
• If the reading is significantly outside the manufacturer’s specified range, replace the heating element.

5. Switch and Control Module Check

• Remove the switch panel from the center console using a trim removal tool.
• Disconnect the switch connector and test for voltage with a multimeter when the switch is activated.
• If no voltage is detected, replace the switch. If voltage is present, further diagnostics may be required on the control module.
