I have 2 sets of 780 seats and none of the recliners work. The problem I’ve noticed on every seat is that the motor spins but is only reclining one side of the seat. I was able to pull the leather up slightly on one of the seats to access the driveshafts and the driveshaft coming from the top of the motor doesn’t spin at all. I tried pushing it in to see if had just come out of the motor but that didn’t make any difference. I think pulling the leather up any further would damage the seat so for now I’ve just adjusted them manually. Here’s a pic of the diagram.
Hey! Thanks for continuing to post questions on the forum. For sure we want to keep things going in here as many folks are posting as well on our FB page.
This problem is almost on every 780 given age. The fix is rather extensive and does require the leather to be pulled up a bit to get to the motors. One side turns and the other is stripped. Here is the best video I’ve found on fixing… https://www.youtube.com/watch?v=lGITgKXCBbg
It is likely where the cable, that had edges like an Allen wrench gets worn and the cable just spins. As shown in the video by cutting back and exposing new cable and sharp edges, it should grip the inside of the motor better. I have never seen a motor actually fail, it is usually just the cable.
