Hey i'm new to having an Infiniti and a car so i don't know much about car's but slowly learning, so my AC/Heater is off and someone told me to buy a new relay that goes under the hood, i came across a few online and i was wondering if it has to be a specific one or are they all same. someone told me as long as it's blue and it's a Nissan one it should work. here's the 2 i came across, i might order the one that's 11.90
here it is
