My 98' Sentra rear defog all of a sudden stopped working. I checked the fuse panel located under the steer wheel and none of the rear defog was blown. I replaced them with new one anyways and it still doesn't work. When I press the defog switch, I hear a clicking sound coming behind the gauge, and the LED won't light up anymore. I checked the fuse panel under the hood and couldnt find anything for the rear defog. Can anyone help??
