I am having electrical issues with my car.
Few weeks back i was surprised with abs, airbag, brake, dtc lights, no power, no remote unlock and all sorts of fun stuff.
I dont have any way of opening my trunk to access my battery without my remote key, but i sorted it out by giving 12V to 2 wires under the glove box (there is a thread somewhere about that). I deleted the faults with removing negative wire after car went to sleep to save my FRM. I used this method because ista and inpa couldnt connect to any module. And everything was fine after that for a few weeks.
Today i tried to unlock my car and it didnt work. Everything is shorting, no start no carnk, all the lights are flashing, wipers are on and i cant turn them off. Battery seems drained and so on.
What are the possible causes of this? My guesses are ibs, b+ shorting somewhere, battery, or some relay. I knkw that its not FRM because i had problems with it a year ago. Does anyone know what to do? Any help would be appreciated.

I had my blower motor recall done in between these incidents.
