I tried to find other posts that might address this but couldn't. I was going out for lunch and my car won't start. I'm not certain that it's the battery because the interior lights work and the windows go up and down - but my battery is old. It just makes a clicking sound when I try to start it. Does anyone know that this could be? If it is the battery, how much do they cost? I've never had to replace the battery in this car. Thanks for your help.
