Battery draining problem????

[cozhavok]

I have a 2004 Chevrolet Tahoe Z71 with 192000 miles on it. After I let it sit for a day and try to start it the next day the battery is completely drained. I had the battery and alternator checked and they are both good. I have no accessories or mods done to the Tahoe it's all stock. The only thing I can think of is there is a short somewhere because the compass and the temp flash on and off along with the passanger air bag warning. Also sometimes the radio will stay open when the door is open and the interior lights will turn off quickly when door is opened or not come on when door is opened? What can I look for? Pictures would be VERY HELPFUL PLEASE

I am new here also and just saw your post disconnect the neg side of your battery hook up a test light clamp on the neg side and touch the disconnected side if the light comes on then there is a draw at this point leaving the test light hooked up begin pulling fuses one at a time when the light goes out now you have a starting point or at least somewhere to start looking. hope this helps.

onstar module is a real ******* for killing battery as well
