if the 240 has the same kind of controlls like the maxima from what ive ben told its like a relay or sumthin in the unit and numbers 1-3 are on the same one and the 4th switch uses a lil more power and theres a chance that number 4 can stop working and all the rest are fine
my maxima right know blows cold 1-3 and when i get to 4 it pretty much turns off , im not sure if its a relay but its some kind of thing ,
but 1-3 and the 4th switch are on diffrent wires i guess you could say , sorry i cant be more help mine went out like a year ago and i never fixed it but thats what nissan told me
btw its a 89 maxima
