Answers :

The proper way to troubleshoot a current drain is to disconnect one of your battery cables, and put an amp meter between the battery and the disconnected cable. Measure how much current is there, and then you can systematically pull fuses out of your fuse panel to see what circuit is drawing power. Some current is expected, such as the keep alive circuit for your radio, and a dome light if you have a door open.
\015\012You should be able to narrow down your search area, by your symptoms. If you have not had your alternator tested, do so, as sometimes they appear to be working, but have a current draw thru the voltage regulator.
To chase down a dead short like your describing you need to disconnect the positive terminal , with it off scratch it over the battery if theres a draw you will see sparks if it has a short somewhere . then take out fuses 1 at a time and test for a short / good luck . sounds like the unlock solenoid is stuck in the up position draining the battery . you can go to a garage and have a load test done on the battery to ensure the battery is good .otherwise sounds like a door panel needs to come off and find the problem. good luck
