I'm having the same issue here. It used to be very intermittent, now its every time I drive. I'm going to try adjusting the seat to see if that helps!

After 6 turns at the dealer it was the harness and harness placement under the seat. Every time I moved the seat when I bought the truck it had crimped the harness and wires underneath, thus shorting the elements off. Finally fixed in the spring of this year, and so far no issues this winter. Elements did not have to be replaced.

@duraj, I’m sorry to read it took so many trips into the dealership to get this resolved, but I’m happy that you’re able to enjoy this feature this winter.
Happy New Year!

New to the forum but had this same issue with the seat heaters.
Problem: Passenger seat heater would work sometimes. Driver would shut off after a second or two.
Solution: The heating element in the back was burnt up and shorted out. It causes some kind of little overload or breaker to shut off causing one or both seat heaters to stop working. This seems to be a common problem and is usually the element in the seat back of the driver seat. I ordered this part number on eBay. SOE Solutions 641-106 Seat Heater Pad.
Replacement is relatively easy.
(1) You don't have to remove the seat.
(2) If you feel under the seat back at the bottom there is a long black plastic clip holding the front and back leather together. Undo it.
(3) Work the leather up so you expose the seat back. The heating element will be right there in the lower back section. Peel it off the cushion.
(4) Follow the wires down under the seat and undo two plastic clips.
(5) Stick the new element on and route the wires underneath and plug it back in.
(6) Your seat heaters should work again.
I also was able to get my motors working on my lumbar and the side flap motors on my seat working again by digging in there and unsticking the motors. I still have one motor stuck to restore full functionality of my electronic seat.
Hope this helps!
