I recently post that i had problems with my radiator fans on my 93 acura integra LS, the small one and the big one never turn on, never.I took the two relays off on the driver side on the side of the radiator. i turn the key on and test if the wiring harness is getting power, and two out of four of the plugs get power. when i run a hard wire to one plug thats hot too the other that isnt the small fan turns on, So after that i take the relay off on the passenger side by the headlight, it is the same way as the little fan, two plugs on the wiring harness get power and the other two dont. so when i hard wire the hot plug to the non hot plug, the big fan turns on. So what does that meen, is it the relays or is it more in the harness, or something else. And how do i perform a test on the relays that i took off. I really need help on this one, its my way too work, SO PLEASE HELP if you could. Give me all the possibilities, and stay in touch, Thanks everyone and have A greaat day.
