Yep, I can help you but we only handle one problem per thread so please start other question for the AC and sliding door issues. We will handle the battery drain on this thread. For the fuses what are they named they don't use a number to identify them. Also I need to ask are the interior lights on as well as the door ajar light? If so it can be a bad pin switch at one of the doors so I would inspect the switch which are located in the door jam. Check out the images (below). Please let us know what happens.

thank u so much for your help. im sorry in my online image it shows numbers,but i found the names for the fuses too, they are 39 Panel, 40 tail, 24 mtr heater. they are all fuses inside the car under the dash. also i have no problems with my tail lights or license plate light or any of the things the tail fuse is suppose to control. the panel i dont know what all it does. i heard that it could be related to the ac problem as well as the mtr heater fuse could be related to ac as well thats why i gave all issues in one question because tbey all started at the same time so i think they could all be related but im not sure. to answer ur question the interior lights work but no they are not on when it says door ajar except when i open the doors and turn them on. so they do work fine.

It is the door pin switch not the door lock and if all of these problems started at once that is a big help for us to fix the problem. How do you check for power at the fuses? If the tail fuse has no power then the tail lights should not work. Also, I was checking the wiring diagrams and these system go through the body ECU which is behind the left side of the dash, I would disconnect the battery and remove the electrical connector to check for corrosion. If that looks okay lets do a CAN scan toy see if the body ECU is bad.
