Check your flasher unit out which is in the fuse box.It should be a round looking unit that plugs into the fuse box.And also check out the fuses to see if you have a blown fuse for the tail lights.You should have one there that says tail light fuse.These are not all that hard to fix to get working the right way.Also take a test light and hook it up near the tail light socket and ground it and probe the socket contacts in the bottom of the socket.But have someone turn on and off the tail lights to see if you got power back there to the contacts in the socket.Replace the bulbs if needed but also clean out the sockets with fine sand paper or a small wire brush.This way you might get a good ground in the socket.Also probe the wire to the socket that is power when the tail light switch is turn on to see witch wire is constant power feed when the lights are turned on.If you have any other questions about this contact me by email at [email protected]
