2003 GMC 2500 HD User Comment / Complaint

I have a 2003 gmc diesel pickup. i have had the vehicle in twice for electrical repairs in the last 9 months. the electrical problems observed include: airconditioner cutting in/out, radio cutting in/out, power windows not working, dash gauges cutting in/out, idiot lights coming on (abs, brakes, check engine etc). it was repaired once by the dealership at a cost of $500. now, 9 months later, the vehicle is back in for the exact same problem. the techniciain took it for a ride and had so many problems, he was afraid he wouldn't make it back to the dealership.
