I own a Nissan Versa and I am noticing it has a high fuel consumption and would like to know if there is something I can do about it. When driving in the city - stopping at traffic lights, heavy traffic, air conditioning turned on- it consumes around 34 liters every 410 km. However, when driving on the highway, I spend 34 to travel 470 km. I understood that on the highway the vehicle should be more efficient, but it is evident that this is not the case of my Versa.

My blower motor resistor was gone so my heat only work on 4 than it gave out completely, I bought a new blower motor and resistor still no air, check fuses under driver side and relay still no air, what could be the problem?!?
