Please Help, need some advise!!! While driving the entire dash shuts down, Radio, digital gauges, turn signals, lights and no power(windows)and the cooling fan starts running full blast! I am getting a error code of P0600 comm. link malfunction, I pulled over and restart the car and everything is fine for a few more miles then it happens again. When i restart car, error code shows "Light Sensor, Visit Workshop" pops. I thought about weak battery since its been 10 or 11 years old. Thank you for any info, really appreciate it!
