Parasitic draw on my Infinity fx35?

Question

I own an Infinity and I've been working on this problem for weeks... There's a switch of some kind that's turned on and is sucking the power out from the battery. If I leave the car off for a day it will not start the next day. I have searched and tested all the fuses but have come to no solution. I need to find out what is drawing the current from the battery but I don't know what it is. It's not the car door's light being on and it's not a blown fuse as I have already removed a blown fuse. The amp meter i use shows a 0.27 draw, but it should be 0.03-ish.

What year is the car?   
Do you have an aftermarket radio? 
Inspect each door plunger. See if they are working. 
Inspect any plunger on the trunk and hood.  Open and close all doors and hood two  times to make sure they are closing properly. 
Open and close glove box. If full junk, fully empty it out. Look for light staying on. 
Fold down back seats if you can, does trunk light stay on. 
Inspect vanity mirrors. 
One problem with testing is that you need to close the door plungers as on a high end car the computer can stay on for 5-15 minutes..just guessing on the time. 
After the inspections for the obvious, you will need to set up a multimeter, close the plungers, wait to computer turns off and pull each fuse and replace, one at a time. 
Note if there are fuses under the hood, and some cars have two fuse sections inside the car.

.03 is normal? Maybe. But .27amps  is the amperage draw of one of my dome lights. That is nothing for a car battery. If that is discharging your battery, you need a new battery.
