door locks

I've checked my fuses and they are good. Any other suggestions? Thanks Chubby

The interior lighting, alarm and door lock system are all intertwined. Diagnosing problems in these systems takes a lot of experience diagnosing electrical circuits. I have years of experience with these types of systems (not on Nissan though) and even though it may be something simple like a switch or broken wire, finding it is what is very difficult. To start with, I get a wiring diagram, focus on one of the problems and try to see where the problem lies. After that one is addressed, see if it affects the others. Sorry I can't be much help, you may want to consider taking this to a shop.
