Hey,

Short history about my car (A8 4.2l v8) bought it 2 years ago. Recently rebuild the trany. I had water leak in my trunk & didn't notice that water is going to the battery composite... long story short battery get shorted it was raining really bad her.. So i drain the water out, dried & cleaned every thing. Replaced the battery and bunch of fuses, the car didn't start so I took it to mechanic and he changed Alternator & some other things to fix it. after 2 week:
1. The battery drains over night
2. The AC fuse blows all the time (Probably short circuit),
3. Radio doesn't turn ON at all
4. AC motor is running even when the car is off (I think that's why the battery drains, not sure)
5. ABS on on
6. engine light on (p0140,p0160 o2 sensor)
7. The car won't start at all again (it might be some relay problem)

I tested all the fuses in fuse box (passenger side) and the one above the battery, they are all fine but i removed the AC fuse.

The weirdest thing that I ever seen was that when I disconnect the Ground off of the battery, but the motor for AC was still running!!!! How that's even possible???

Can any one please help me?
any suggestion for how I can start my car would be appropriated
