Hello. I have a Toyota Corolla 1999. If I forget to turn off the radio or the AC or the radiator before I switch off the car, the next time I'm going for a drive, the car doesn't start. The battery has run out or something. Can someone help?

Remove and fully charge, or replace, the battery. Most auto parts stores will charge batteries for free.

Has your radio or radiator fans been rewired other than the way Toyota wired it?
Meaning: what is aftermarket on this car?
