Question about 1997 Pontiac Sunfire
It doesn't matter if the engine is hot or cold when you bypass the relay. The fan should come on. Did you try both ways on the relay. One way is for the fan the other is from the computer. just to make sure. If the fans do not work then it is most likely the fan. I would check the fan when I had it apart. to hard to do it in place. you don't want to replace it if it is not bad. It could be from the computer side . ie. bad connection, bad computer, bad wire. need to check. also to check the relay connect a wire to prong # 30 and #87 Between + and -, you should hear it click, and while it is connected there should be continuity between prongs #85 and #86.
