I just need some back up with electrical problems. Rear wiper, rear defroster inop; good continuity through the wires; fuses good; cannot figure out what pins on the switches to test, I tested all pins and no continuity. I am thinking that the switches are bad. I know that almost all my dash lights are out. I guess my biggest question would be,where can I find a full electrical schematic for my 1995 Diso I?
