The right part of driver's seat thigh support of my sports seat super heats

. I have found that if I extend the thigh support, the heat spot goes away, and then after bringing it back it still does not heat up super hot. But when cleaning the seats and moving the support back and forth, it comes back. Extending it again "fixes" it

. I'd like a real fix - it seems a simple one in my case, but I lack info.
