I have a 2005 Chevy Impala. My gas gauge hasn't worked since I paid off the car.

What is your question?

I replaced the fuel pump and the sending unit(I think), and still doesn't work. My windows will roll up or down only if I have the driver side door completely open. Sometimes after turning off the car I have to go open and shut the passenger door to turn off the music. Sometimes the blinkers will stay on instead of blinking. Feel like I'm driving Christine somedays. I am tired of putting money in this car, so I am hoping to find an answer here.
