If the driver's side seat adjustment and lumbar buttons are not working, and the seat heating/cooling button is not responding correctly in your 2003 Lincoln Aviator, there are a few additional checks you can perform to further diagnose the problem:
Check the wiring connections: Ensure that all the wiring connections related to the seat controls and heating/cooling functions are securely connected. Sometimes loose or disconnected wiring can cause such issues. Inspect the wiring harnesses under the seat and check for any signs of damage or loose connections.
Test the seat control module: The seat controls and heating/cooling functions are usually controlled by a seat control module. This module could be malfunctioning, causing the issues you're experiencing. A diagnostic scan tool can be used to retrieve any error codes stored in the module, which might provide insights into the problem. Consider taking your vehicle to a mechanic or a dealership to perform this diagnostic check.
Inspect the buttons and switches: Examine the buttons and switches themselves for any physical damage or wear. Sometimes, worn-out buttons or switches may not make proper contact, leading to a lack of functionality. If necessary, the faulty buttons or switches may need to be replaced.
Test the seat motors: The seat adjustment and lumbar functions are controlled by electric motors. It's possible that one or more of these motors have failed, resulting in the non-functioning buttons. A mechanic can test the motors' operation using a multimeter or by directly applying power to them to check if they are functioning correctly.
Check the climate control module: The seat heating/cooling function is often integrated with the climate control system. If the button is not responding or displaying the incorrect status, it could be an issue with the climate control module. Again, a diagnostic scan tool can be helpful in identifying any errors or malfunctions within the module.
