i blew my interior light fuse the other and replaced it but now the door option doesn't seem to work. Its either off on and on it doesnt seem to turn off when doors are closed. any suggestions what it might be ?

 

Remove each door switch and check them for an electrical short.

 

I was able to remove all the door plugs or sensors or whatever they called. my question is do i check the plug itself for elctricity or the line its pluged into. and also how do i do that with a basic fuse tester that light ups if it works?

 

Test each disconnected switch with a continuity tester. In the "door-closed" switch position there should be no continuity between the two terminals whereas in the "door-open" switch position there should be.
