If he battery needs to be 'replaced' you should try that first. Also, you could be having a problem with the Alternator. At 15 years old, this should not come as a surprise. Also, a bad alternator is a serious safety risk, that can mess with any electrical system in the car: turn off brakes, turn off steering, de-prioritize AC in favor of defrost, etc. Hope that helps, good luck!
