ok so i have been working on my 87 300zx and this problem appeared my floor interior lights are on and are allways on killing the battery.the only way i can turn them off is to pull the fuse to the interior lights. i thought maybe it was the drivers side switch seeing as the d/s door light was burnt i couldnt check going to get a new light now though.anyways when i close the pass door the door light goes out. so i figured if i get a new d/s light and it goes out it isnt the switch wich i allready replaced.so i was wondering what else could it be?

anyways thanks for any input or tips you have appreciate it greatly.

[edit] new bulb and still d/s door light wouldnt come on replaced the switch with pass door switch wich i know to be good and the floor lights still wouldnt go out

 

trunk switch maybe.
