John Deere 7775

[Skier125]

I got a john deere 7775 with in cab heat and got the heat working left the heat running went to put back in the heat switch panel made a big spark and the heat isnt working any more any ideas. I was think of taking the two positive cables putting them together to see if I burnt the switch. Any Ideas how to fix this? Thanks for help here is the diagram of it. http://www.dowdatractor.com/pages/o...ONAL:_ELECTRICAL/24140003/2414D210D0304000018

Is it possible that the contacts ont he switch were a little dirty causing it to get hot and melt causing it to short out? If so, replacing the switch should fix the issue.
Even hook up the motor to make sure its not shorted out too. They can lock up and blow fuses, but it shouldn't cook a switch.

Either fuse or relay or possible blown switch or fan moter. Hate to state the obvious but that's all I got.
