Get an ammeter that can read milliamps.

Close all the doors and make sure the ignition is off.

Remove the negative battery cable.

Connect the ammeter in series between the cable and the battery negative post.

Read the meter. It will probably be somewhere above 100 milliamps.........maybe more.

Remove the fuses, one at a time, until the meter drops down below 60 milliamps. One of the fuses will be the clock.........so........be somewhat aware that the draw from the clock is normal........about 50 milliamps or so.

You are looking for a fuse that draws 100 milliamps...........it could be as hight as 300 milliamps with a serious leak.

Once you find the circuit that has the excessive draw, repost and we'll see which one it is.
