3 amp draw killing my battery!! Please help!!

[bl_rdrgz]

Alright guys so here is my dilemma I have a 3 amp draw on my battery which is killing my battery horrendously. I started checking fuses and my draw is usually about 3.11. But when I pull fuse 20 in the passenger kick panel (FEM,DATC,Cluster,REM) the draw drops to .76. Which technically speaking is still to much in my opinion. My datc didn't work so I checked the #1 fuse in the engine compartment and the fuse was good but looked corroded somewhat.So I changed the fuse and now my datc works! But.. I still have a draw. So that didn't fix the issue.. Any other recommendations? Any help is greatly appreciated.

A few points.
1. Troubleshooting a parasitic drain without dealer (or equivalent) scan tools is nearly impossible. The dealer tools make it a lot easier to find out which modules aren't sleeping and why.
2. Pulling that fuse may cause the SSP relays to open, which could mislead you about where the drain is.
3. After you do anything, you have to wait twenty or thirty minutes for the car to go back to sleep before the current reading drops to what it really is.
4. Three amps is really high. That's 36 watts. You should be able to find something getting hot.
5. The DATC fuse probably blew because your DCCV is starting to fail. You'll be wanting to replace that.

No the fuse did not blow.

Well, you said you changed the fuse and it made a difference. If the fuse was open...

No. The fuse looked somewhat corroded. So I changed it. So now my datc does work. But the amp draw did not change.
