I own a 2002 Chevy Cavalier. I've been having problems with it lately. First off my heater / air conditioning doesn't work on any lower settings only the highest setting. Now I've been having problems with it starting, it doesn't even make the clicking or buzzing noises and its not the battery. I can jump start it but when I start it the trunk pops open! Please help! I think it might be a resistor but would that cause all of these problems or is there something else too maybe? -Jackie
