My battery finally died, after 4 1/2 years, no big deal.... Ever since I got my new battery, nothing electrical works right in my car!!!! The interior light will not come on when I open my door. I have to turn it on myself if I need it. This is annoying at night!! I want my light to come on when I open my door at night!! Also my radio will not turn off, even after I take my keys out and open/close my door, I go shopping, come out and the radio is still on!!!!! Also, it seems my gauges started to go nuts soon after. Whats the deal???
