You need to do a battery drain (parasitic) test/diagnostics. Look in the Electrical Sticky above or Google for it. You might need to have an electrical friend help you. In the interim, make sure you operate every switch you can in case you have something hung up, especially the seats. If you have someone who can help you I would be glad to give them guidance on this, including how to separate the diagnostics between the Engine and Passenger Fuse Boxes by disconnecting the tie between them.
Also put your hand on all the relays in both fuse boxes and see if anything feels warm/hot.

My 99 GMC was doing the same thing. Would be fine for weeks then dead, sometimes sooner, drove me crazy. Turned out one of the hinges on the visor mirror was faulty and allowing the light to stay on causing the drain.

Care of Bill Curlee:
STOP!!!!
Never hook a charger directly to a completely dead battery and attempt to power up the electronics in the car!!!
Your battery charger is NOT pure DC. Its rectified DC and in a square wave. That will possibly damage your modules. The battery acts as a filter and if its properly charged, you will not see the pulsations and or chattering relays.
Remove the Neg battery terminal and then the POS battery terminal, remove the battery from the car. If you can, check the electrolyte level in each cell.
Try to charge it with a standard (non computerized ) charger. Monitor the charge and see if it will come back to a normal charge
