I have a 2004 chevy Silverado LT duramax. My driver heated seat stays on for a second and cuts off but you can use the passenger side and it will stay on if you don't use the drivers side.
But if you use the passages side and
turn on the driver side it cuts both of
them off any ideas I have checked
the fuses and they are good and I
still replaced with new to be sure and
still same thing happening any
It may be in the switch,and all so check the wiring harness under seat.
seat relay or seat heat coils need replaced.
