Battery Draining / Room fuse - Help

So here's my problem...... I noticed that my battery has been dying on a regular basis. I had the bat/alternator tested and tested again as good. I pulled all fuses and started testing using a test light..... I then found the ROOM circuit was lighting up the test light!!!

Anyone have any ideas where I should look for what’s causing it? I looked at the Electrical section of the FSM and didn't see anything useful.

Thanks.....

Do you have aftermarket radio or anything of thing that required splicing the harness? when i installed the radio myself my harness was messed up and it didn't work. i left the radio harness connected onto the car harness and it end up killing my battery and blowing couple room fuse

yeah man the biggest source of electrical drains I have encountered on these cars are the headlight motors (but only if you get into a mild car accident. the headlights will try to go down but they can't completely due to bumper damage) and aftermarket wiring. Check for any uninsulated wires, bad crimps, etc.

ok..removed radio removed all wiring, Room lite fuse circuit still lighting up with test light.....Strange thing though seemed like the alarm was going off, horn honking when I depressed the door jam sensor and had test light connected. I say 'seems like the alarm going off' beause I never used it and dont know how. I will try disabling the alarm to see if its the culprit.
