The driver side seat heater is not heating. The switch is O.K. The fuse is O.K. Is there a relay and if it is where is the relay? Could there something else wrong with the heater?

Had the pleasure of working on these beast when I was a GM tech......without diag paper work your shooting in the dark but most of the time it was the seat cover that has the heater in it that was bad .......the module for it is under the seat on the side ..........to replace the heater element the seat cover will need to be replaced..........
