Part Time Computer Jobs?

I'm currently a student and have completed most of an Electrical Engineering Associates Degree, but am also interested in Computer Science. Most of my work experience thus far has been in retail and I would like to do something related to what I actually enjoy doing. I'm not really sure how to begin my job search, though. Unfortunately, I don't (yet) have any professional credentials. What sort of jobs should I be looking into at this level?
