On mine, it's the fourth relay from the inside out. In case they are in a different order, it should be the relay with two large wires and two small wires coming into it. One of the large wires is power and the other goes to the fan. One of the big wires should be purple with a black stripe. Spray WD-40 into the socket before plugging back in. This has been a BIG problem spot for GM. The wiring, not the relay, is what causes the problem. the contacts get hot and lose contact, then get hotter and quit working completely. I your connector looks burned, it may still work if you use the WD-40. The relay may still be good, too. This cost GM a lot of head gasket repairs due to stupid engineering and overheating. Typical GM.

Your coolant light of your 97 sunfire 2.2 came on and it is full with radiator fluid what else can this be the light wont go off?
There is a sensor that is in the overflow bottle that may be bad causing the "low coolant light" to illuminate. The coolant level switch is located on the bottom side of the coolant tank. The switch contains a reed switch and a magnetic float. When the coolant level is normal, the float rests away from the reed switch, causing the switch to be open. When the coolant level decreases in the coolant recovery tank below a specified level, the float rests on the reed switch and the switch closes, illuminating the LOW COOLANT light. The coolant level switch is a part of the coolant tank. If the switch needs to be replaced, the coolant tank must be replaced.
