Just hauled my new 2015 XP900 Hunter Deluxe to my hunting camp (400 mile from home.) I tried the seats several times, no heat. I hit both buttons and they light up, I look down after driving and notice one or the other is flashing and I cant turn it off. No heat. I turn off the machine and turn it back on, still flashing. These are factory installed heat seats, am I doing something wrong?
