which way are the altima fans supposed to spin?

currently my altima fans are supposed to be spinning on high speed(both), they both spin the opposite way of the stock mechanical fan, and am concerned that i don't feel that much air comin out of'em(supposed to be pullers), but i can feel air on the front side of the radiator, not sure if sucking or pushing.

if the fans are currently on pushers, what is the correct wiring for them?(pos & neg, setup is goin to a switch for both neg's which turns them on, both pos go to battery pos+)

this is a 93 240, 95 rad, ~93-94 altima fans(white blades).

Altima fans are pullersWill only spin one way.If you want to use only high speed, you wil need to join both pairs coming from each motor and energize themPost wire colors if possible.From top of my head, yellow, blue and black?they will rotate counter-clockwise if saw from the front.

f u reverse the positive and negetive as in switch what there connected to the fans will become puller.... make sureu have the +/- hook up where there ment to..

heres a test take a good peice of cardboard and see if it gets bloawn away from the fans or suck into it.. thatll let u know if there moving right.. u want the fans to be blowing the air onto the engine so there are pulling the air through the radiator

If you change the flow of current threw the fans ( change the pos. and neg.), they will change direction. As of right now, they are spinning counter clockwise ( the opposite of the stock mechanical fan.)

Weird, when I was checking my wiring, fans only spin one way only...I know that aftermarket fans will change direction and altima fans should do the same.
