Ok gurus. Here is the problem. I got this car and the po said she shorter out the battery when jumping it. Now there is no interior power. She caims its the ecu that is causing this and a relay. Where do I start to check this? Please call or text me at 551-804-1684.

check fuses?

I replaced every one in that car. The car has 0 power. No light, chimes, 4 ways. No click when you turn the key. Nothing. So what relay? What wires?

That fixed that problem. Now there is no cel or any power to the drivers seat. Is this from a faulty ecu? The cel that is. And what relay is the drivers seat?
