My front row vents dont blow cold or hot air but the back seats do. on 2010 Chevrolet Traverse

I checked the fuses but they seemed to be ok. I have had nothing but problems with the air conditioning and heating system in this car. What would cause thefront seat fans not tork but the back seats still work fine?
