Followed this tutorial yesterday only to discover all my wires were intact with no obvious burn marks on the lower cushion. Are there any other common faults that I can look for? I have already checked the fuses. I thought I recalled, something about a relay that should click under the driver seat when you hit the button. Otherwise, I am assuming the fault could be in the upper element of the heater? I had no idea how to get the upper seat degloved.
