Replaced seat cushion with new one yesterday. $125 not that much of money. It is sided to a certain degree. Seat controls recess plus some shape in the far back of it.
Took about 2 weeks to arrive.
Total time around just over an hour. Plus, I had to go to O'Reilley and buy deep Torx socket set. Thought I had all of them from my Silverado times, not the case.
Anyhow. I removed entire seat, it's much easier to work on it than in the car.
I could not get to the center console flap side, without actually removing seat from the frame, that flap is fully covered by frame. But, fabric pulled back enough to have cushion removed without any major complications.
Found that heating element folded into harmonica shape in its back section and fabric had burn marks on it. Apparently, as waves of it pressed against each other, they got shortened and caused higher temp. Amazing, it still works. Took some time to carefully straighten it and then I secured it in place with glue not just at the forward edge but, across entire cushion.
Nothing really special about reinstall. Plastic clips that go into cushion groves took some wigglige but, otherwise, it's just patience and strong hands.
I almost regretted I did this though. Set in the seat and head hit the ceiling. It raised me up that much. Well, I am 6'2.5'', so had to decline backrest.
Otherwise, pretty good.
