I found the same thing over the years , rear cluster turning to dust , the pintos were made here and Canadian pintos had the crapy cluster parts, look on the door striker by the ID tag you will see a round blue sticker saying that it was make there, next you use the back cluster part you just brought and use the printed plastic board from your old one, if it still does not work your proble may be to other plugs or switches, mostly the ign switch, part of it gets burned out or over heated if your car has A/C and the fan motor is drawing too many amps and heats it up, yes it may crank up but other thing like turn signals , warning lights ,etc will not work , hope this helps you , later Blaine
