I have a Nissan sunny 1.4lx auto 1993, just found my rear number plate lights not working, have changed the bulbs and checked the fuses but eveything is ok.Any ideas as to why they are not working and what else I could check. All advice appreciated Thanks Ray

 

Did you check for a good ground? If ground is OK, I'd use a test light and see if power is actually getting to the light. Then go back up the harness from there.
