I have the same exact problem. Mine worked last winter and now it doesn't so i don't know what'* going on. I took my seats out to thoroughly clean under them but im not sure if that affected things. Thanks for the link Archon.
hahah i read about that far and thought to myself; "once the passenger side goes out i can pull the plate with the switches in it and then knock the switches for heated seats out and fill it in, sand and repaint with color coat"
Nope, your seat has a cover on it..........look on the side of it. It is attached with black clips that simply come off when you put some down pressure on them, then lift out and up. The cushion stays in place. The bad heating coils are imbedded in your cover, just cut the connectors off and then the replacement coils come as stickons. Normally it is only the bottom of the seat that is bad, which causes none of the elements to work.
