Hi, I have a 2002 galant, the other day I walked out to my galant and the left blinker was flickering fast so I opened the door and the light on the dash that indicates that the door is opened was flickering at the same pace, the lights were off and cars battery died due to that, I popped open the hood and the blinker and door indicator were still flickering but also I heard a clicking at the same pace as the lights from the ECU, I unplugged the ECU and placed it back and jumpstarted the car, the car was on and running normal, but, every time I turn on the car the radio resets, the dome lights, trunk light, door and chime indicator weren't working anymore also the power locks only work when car is on, I checked the fuses for the dome light which powers all of those options which is a 10 amp fuse and its good and new, I tried following the wire from that fuse but can't find where it leads, I've found people online with the same problem but there fuse was burnt out, my fuses are new, I made sure

Check fuse and if not wiring if not buld and I would re wire it from the battery
