Wiper circuits can be fairly complicated, especially for a novice. You should buy an inexpensive digital volt, ohm meter and learn how to use it. A 12 volt test light is another handy tool. The best tool I have found for 12 volt systems is a power probe as you can easily test positive and negative conductors to a load, across fuses and switches. You need to find out if you have power getting to the load and if not where are you loosing it. make sure you have a good negative or ground getting to the load as well.
Best advice I can give you is to find someone that can diagnose the issue and is willing to train you in the process. Good luck and keep us posted.
