Hi Troy, my name is ***** ***** will try to help. What do you have for body controller faults logged in the dash display?
Code 42 :
Possible calibration not performed with an ECM installation or cam to crank timing or backlash problem. Happens after a cam, head, or front cover have been removed and installed. This code means the ECM is detecting more than a 3 degree difference between the cam and crank sensor. The solution is to correct cam gear timing or back lash.
Code 58: Datalink connection fault. A problem or loss of datalink communication has been detected.
For your wipers it sounds like you could have a short or bad ground or bulkhead module issue. Bulkhead fault codes are different from engine flash codes. I will post a link to help.
