Same here, only costs 25 cad to order the element. Take me three hours to replace it. (Tips: alcohol can help when removing the old mat) This is the first car I have had a heated seat issue. My old 2013 Fusion has a much better build quality than my 2020 Explorer.
The thermistor in my heating pad disengaged, causing the pad to desolder after heating up like crazy. Ford simply used hot melt adhesive to hold it in place. The new heating pad seems to be better quality hopefully I won't need to replace it again.
