The radiator fan on a Saturn should give you years of trouble-free performance. However, over time, several things can go wrong with it. When the radiator fan does not work, this is a serious problem. The fan helps cool off the radiator, which acts as a heat sink drawing heat away from the engine. If the fan is not working properly, the radiator will not properly cool the engine. This, in turn, could cause critical engine components to fail.
Check the fuse for the fan and relay. Remove the fan fuse under the dash. Open the fuse box by turning the knob on the fuse panel cover counterclockwise and pulling the fuse panel down. Remove the fuse for the fan with the supplied fuse puller (on the underside of the fuse box panel cover). Check to make sure that the fuse has not failed. The fuse contains a metal strip in the center of it that should be intact. If it looks burnt or is broken, replace the fuse with a fuse of the same amperage.
