So I bought a 2000 Nissan sentra, its in pretty good condition, but my cruise control doesn't work 98 percent of the time! When I turn it on the light comes on, but when I hit set nothing happens!
Also my cd player barely works. Sometimes I will get it to turn on, but half way through the song it shuts off.
My power locks for the doors have never worked, since I got it. And neither has the inside light.

I've checked all my fuses and they are fine. I was thinking that there is some electrical problem causing everything, but wasn't sure what. So if someone could tell me whats wrong with it, or what to look for, I'd appreciate it!
