2004 GMC Sierra 1500 Z71 Drivers Side Heated Seat

[MLong]

Well I would like to start this off by saying I know wiring issues can be a pain to figure out and of course I think I might have a wiring problem. As I returned home from Christmas Vacation I jumped in the truck and started heading down the road and then I noticed that my A$$ was on fire. So I look down and sure enough the heated seat was on for the butt and back rest. Well I turn it off and said something to my wife then bam it's on again. So at this point I have decided that my seat is possessed because it just keeps running through the heat settings. Does anyone out the have any pointers on where to start troubleshooting? Thank you for your help in advance.
