To check for a draw, take one of the battery cables off the battery and put a test light between the cable and the battery post. It doesn't matter if it's pos or neg. Make sure everything is turned off and the doors closed. If the test light is on, you have a draw. The brighter the light is on, the bigger the draw. Start pulling fuses as mentioned until the test light doesn't light up. You have found the circuit the draw is on. Then go thru everything on that circuit until you find specifically where the draw is.

Do this but use a multi-meter set in amps. That way you can tell how much you have for sure. Anything more than 50 milliamps is cause for concern. Test lights may not light and you could still have too much draw. Make sure you wait about 1 hr after shutting doors, etc...to let the modules go to sleep. Then take reading and pull fuses.
You can use a mulit meter, but a test light will also work. If you can see it light up, it's drawing too much. If you have a draw that is causing problems, you will see it with a test light.
