only one taillight not working

Hi,

Which side is not working? Also, with the lights on, does the license plate lamp work? Does the side marker lamp work? When you checked fuses, did you conform there is power to and from them? If you haven't checked for power at the fuses, that needs to be done. The fuse could be good but not receive power from a fuse ahead of it.

Let me know what you find when checking for power, which fuses were checked, and which light isn't working. Also, note if the license plate is working, specifically if the problem is on the left rear (driver's side).

I will watch for your reply.

Take care,

Joe
