The bottom and back heater pads are wired in series (6V heaters), which is why they would both go out together.Well, I switched relays between the two seats and the drivers side still won't work. I guess its the seat heaters. Wonder why both the bottom and the back went out together? My starter bendix sounds funny, seats won't heat and I need a set of tires, time to trade.
Very common issue. Just fixed it on the Excursion. You can pull back the leather seat cover on the bottom front and take a look. Don't be shocked to find the remains of a fire...I have heard that the driver's seat wiring goes bad where the top and bottom pad connect from repeated reclining. Anyone know of any validity to this?
When my 09 F550 drivers seat heater went out, the dealer replaced the drivers side element on the bottom cushion. It went bad @ about 20K miles, and was replaced under warranty.Well time to bump this up!!
My driver's side seat heater quit working and the other still works. Has anyone had these repaired. I hear the click of the relay and the switch light comes on.
