89 Buick Century cooling fan relay

Does anyone know which of the 4 relays on the front of the car is for the cooling fan? I have tried chilton's and an online search to no avail. Thank you any and all in advance

i belive it was the 3rd or 4th on mine easyest way to tell is to just get a multimeter out and test for a bad one

The cooling fan relay on a 1987 Buick Century is mounted inside the hood on the driver side strut( the gray mountain thing with a black cap near the firewall to driver) there are 3 relays there the left two are small single plug blocks. The right most of the 3 has two plugs and a number of i think 10045587 or something and is the cooling fan delay relay. Hope that helps.
