Turbo_Bimmer, thanks for the info.

Due to the temperatures out there it's a bit hard to measure the resistances currently yet alone pull the whole seat out of the car.

I took the aftermarket pad I purchased off eBay and measured it's resistance and it reads 10k on the dot.

If this is the case, no matter what my issue is - broken heating grid or sensor broken shouldn't I be able to just take this pad and install it under my seat and connect these 3 wires from it to the OEM system and off I go?
