Ive searched and found threads on repair for the elements, mostly on the zj. My xj has seated seats as a factory option and they have never worked all these years.
I had a go today with a multimeter and found tbe open circuit but still aint going.
If I get one of those carbon aftermarket ones, will they be felt through the pillow padding sewn into the leather cover? Its about 1/4" thick which sits on top of the actual foam cushion. I could pull the padding out but sewing it back up might be a problem.
