Why does my car do this?
 

Ever since I can remember my odometer hasn't worked that well. It will only come only like 30% of the time and the other 70% it is just black. Why is it doing this and how do i fix it?

First thing I would do is take the gauge cluster out and make sure the connections on the back of it are on tight.

I've done everything to try to remove the dang light switch. I've tried a screwdriver, nail, small piece of metal, everything! It's just not possible, i swear i have a broken switch or something.

bulb maybe?
