In my sons 1993 300zx there is an electric accuator located behind the door handle, his was broken, need to remove door panel to acsess. In my 300zx, there are 2 cheap plastic black pieces connecting a set of 2 metal rods (one going to the back of the door and one going into the door handle/power) You have to disassemble the door to get to it, try replacing that if it's broken or not even there.
The fuse box.
