Ford F-150 passenger power door lock not functioning, causing fuse issues and intermittent unlock failures on Ford F-150

Some Ford F-150 owners report experiencing issues with the passenger power door lock, including malfunctioning locks that lead to fuse problems and intermittent unlock failures. These issues may stem from mechanical and electrical faults, such as a low key fob battery or a faulty key fob affecting central locking. Additionally, if the passenger door fails to lock or unlock, it could indicate underlying electrical problems. Some owners find that the root cause may be a defective door lock actuator or a shorted wire, often located in the driver door jam or floorboard. Repairing these issues can be costly, with door lock actuator replacements ranging from $160 to $250, plus labor. Regular maintenance, including proper lubrication and checking the door lock actuator cable for tightness, can help prevent these problems and ensure the system functions correctly.
