Question
I have A 1992 Buick Century 6cylinder. I would like to know which relay on the fire wall go to the fan. I wont to check that before I change the fan motor          THANK.

Answer
Its the one with 2 heavy gauge wires, a red one and a black one. It will also have 2 or 3 other wires going to it but I dont remember the colors. They are not always in the same location on the firewall, and sometimes they are on the core support behind the left headlight.
