seat warmer

I recently purchased a 2011 Ram 1500 Quad Cab Laramie 4x4. When I push the seat heater or cooling buttons for the drivers seat, passengers seat and rear seat the lights come on for a couple of seconds and then go off. The heated steering wheel is working. Is there a relay in the system...

So on this 8 degree day in Boston I am having a bit trouble with, of all things, my heated seats. When I press the driver side heated seat button, It will light up for about 5 seconds and then turn off. The seat does not warm up. The passenger side heated seat works properly.. Any ideas...
