Re: Rear defroster wiring?
I knoiw there has to be a relay somewhere(probably under the dash) for the defrost or, like you said the switch would probably burn up. I am trying to figuer out what the diode assembly, that is right beside the battery, is for and why one wire from the defroster is tied into it. IT has one from the a/c and a black wire that hooks into the computer, these three are conected via a circiutboard to individual diodes. Then it has another wire from the comp and one from the sol-vac idles relay that are hooked to 1amp miro fuses in the circiut board. If anybody with a FSM could post or email me the complete circiut It would be a great help.
