I've been through the forums and manuals and have had no luck. Neither my key fob nor manually pressing the door lock button will activate the door locks for my front driver and passenger door. This started as an intermittent problem, and initially I thought my key fob battery was low. However, manually pressing the door lock or unlock switch no longer works as well. Pressing the key fob will lock and unlock my back doors. Would this be an actuator or a fuse? Or something else. If actuator, why would both front doors fail. If fuse, I've opened the fuse box and can't seem to locate one fuse dedicated for the front doors. Thank you,
