I'm trying to figure out what's wrong with my Mom's car, a 2002 Buick LaSabre. Here are the issues: First, windshield wipers would not turn off (for a couple of weeks) even when they were in the "off" position, now the windshield wipers won't work anymore; the emergency brake light stays on when the emergency brake is not set; the ABS system warning light is on (and has been on for months now); the car starts some times and some times it won't. My experience is that it doesn't "sound" like it's trying to start. There is a little click sound though when trying to start the car. Any suggestions?
