I've read alot of articles and posts but I'm not that good with electrical stuff. I have power all the way back. Window doesn't work from switch or key. Nor does the wiper. My license plate lights and washer motor work. There is one wire that goes into a little black box that has power on the upstream end (i can hear the relay clicking when i touch the two ends together)yet when its hooked up my test light doesn't light. Is it the window motor that's bad or is that little black box bad? What are some other checks I can make?
