My defroster works sometimes, but now the switch intermittently decides to start flashing and buzzing for no reason goin down the road. I want to just hook up a different switch for it but I don't know which wires from the plug I need to use, from what I can find blk/yel is the power but what are the rest, it has 5 -6 wires on the plug. I'm sure someone has a helms can help me out, I have a chilton and haynes but neither shows more than 2 wires.....anyone?

 

 

Thank you this is what I needed. This is the best forum I can always get help figuring out my problems
