Hi, i have a couple of questions.
I was checking something with my AC to see how cold it was so i turned the car on (engine off) and was checking the AC. Only for about 2-3 mins tops. And then after i shut it off, i tried to start the car and it died. Does that mean my fans just drained my battery? Also before , when i tried turning the car on with the AC on 2 it didnt start. Any help will be nice thanks, its a 94 eg hatch si canadian model running a D15B vtec.
