power door locks do not work using locks located on door?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If the power door locks on your MKX are not working with either the door lock buttons or the key fob, several potential issues could be causing this. First, check the fuse related to the door locks to ensure it hasn't blown. Next, inspect the wiring harness inside the door jamb for any visible damage or loose connections that could affect the lock actuators. Sometimes, moisture or corrosion in the connectors can also cause issues. If these checks don't reveal the problem, diagnostic testing with a multimeter may be required to check for voltage and continuity in the door lock circuit. A qualified technician can diagnose the issue accurately and recommend the necessary repairs to restore proper function to your door locks. Good lock! (see what I did there?)
