Cadillac Repair: Electronic Problems, electronic problems, drawing power

Question
We have a 1999 DeVille.  The battery in the car went dead, bought a new one and it went dead too. I noticed that the radio would not turn off when you get out of the car it seemed to be drawing power even when the car was turned off.I charged the battery took the car to a Caddy dealership.  They charged us $340.00 and said that the radio was the problem and they removed it from the car.  Brought the car home, the radio is still not in the car and the next day the battery is dead again. Recharged the battery, pulled the fuse for the amp, car starts the next day. Reinstalled the radio, but when the radio is turned on, it still does not
turn off when the door is opened even with the fuse removed for the amp. You can turn the radio on without putting the key into the ignition. Now I have noticed that you can also operate the power windows and sunroof without the ignition switch on as well. The interior lights of the car are also not coming on when the doors are opened sometimes and at other times when you open the doors the interior lights do come on. When the interior lights won't come on, if you use the remote to unlock the doors, the headlights won't come on either.  The headlights do come on when you use the remote control when the interior lights are working.  For some reason, things are still receiving power when the ignition is turned off and it is draining the battery.  Any suggestions?  Thank You.

Answer
There seems to be a lot of this identical problem going around lately and the cause seems to be with the illuminated entry timer and the RIM module. This will require replacement of both components and directive illustrations showing you where and how to replace these components. The usual guy I would send you to who can draw pictures very well and e-mail them to you is sick. The only other person that I know of would be to e-mail: cadillactech@hush.ai
