I have a 2005 Chevrolet Uplander 4WD. In the past week I needed a new battery. Then all of the sudden, it seems like everything stopped working like a domino affect. My turn lights went out, no power locks, doors or windows. The power seat also stopped working. I looked at the fuses underneath the hood and noted that 3 fuses were blown. They were the main battery 2 and 3 both 60 AMP fuses. Also was the . Also blown was the front blower HI 40 AMP fuse. The fuses were replaced and the vehicle was running great with all components working properly. Then a few hours later as I was driving, all three fuses were blown. Can anyone tell me what the problem could be? I would appreciate any and all input.
