Truck wouldn't start so purchased new battery at dealer. Seven months later same problem so dealer had it towed and replaced the battery again, and tightened the cables. Then two weeks later same thing, dealer towed and kept truck for a week, said it must be the alternator. We purchased an alternator and two days later dead battery. They have had the truck for 8 weeks and now they tell us it is the fuse box? We have had everything disconnected, GPS, OnStar,

Radio,and anything else that made a noise while just sitting. They say the radio fuse is causing a drain on the battery because of the contacts, every bump or even door closing causes it. I'm tired of putting money in this truck and still no definite solution. I don't feel I should pay for a fuse box and have the same thing happen again. The dealer assured me it was the alternator and here we are 8 weeks later. We didn't need the battery either. I would like my money back for the purchases I didn't need, as now I have to pay for a fuse box. Please help!
