New here , thanks for letting me in . I have a 1989 IROC , 5.0 , TPI , 5 speed manual . I was working on the A/C last week and noticed neither of the radiator cooling fans were working . The driver side fan comes on as soon as you start the car but shuts off immediately after starting whether the a/c is on or not .. The passenger side fan would not come on at all whether a/c is on or not . After doing a little research I found the cooling fan switch down between the number 6 and 8 spark plugs . I can unplug it and ground that wire and then both fans work with a/c on . According to things I read this means my wiring and the relays are good . If that is so where does that leave me ? All input appreciated . Thanks
