There could be a number of reasons why the tail lights on your 2017 Nissan Altima are not working. Here are a few potential causes to consider:
Bulb issue: One of the most common causes of tail light failure is a faulty bulb. If one of the bulbs has burned out or is not functioning properly, it could prevent the tail lights from turning on.
Wiring issue: Another potential cause could be a problem with the wiring for the tail lights. If the wiring is damaged or corroded, it could prevent the tail lights from functioning properly.
Fuse issue: The tail lights may not be working due to a blown fuse. Check the fuse panel for any blown fuses and replace any that are faulty.
Tail light relay: The tail light relay is responsible for supplying power to the tail lights. If the relay is not functioning properly, it could prevent the tail lights from turning on.
