has this happened to anyone?
brand new battery , i left the car unplugged at approx -15 celsius weather overnight , it was completely drained i couldnt even boost it to start

its common for these cars to not start without being plugged in?

my other ride 99 cougar i never plugged and it started

thanks the car is a 95 blazer

 

I had a huge problem with mine when I got it. Had a draw somewhere. Here is where I found mine which is common for blazers. The pass side makeup mirror. It has a light on it, and the button sticks, so when you close it, the light stays on but you can't tell because it's covered. I found this by testing and pulling fuses, and finally found that bitch...
