05 crossfire. System is charging and battery is good. However, rear left taillight stays on constantly when car is off (turns off once cranked up) and the battery drains within an hour or 2 and has to be jumped everytime i drive. I removed fuse 9 when this started before i realized light was staying on. It stays on whether i lock the doors or not. When i turn lights on both taillights work, but when powered off only left side stays on. Any idea where it stems from? I thought at first alarm system but that doesnt explain why it happens when car isnt locked.
