In the radiator there is a sensor about 1/3rd of the way down from the top with 1 wire connected to it. When the sensor goes bad the low coolant light stays on. On our GM products replacing the sensor in the radiator turns the light off. The wire from the sensor to the dash light could have a bare spot in it and be touching metal witch would turn it on but I have never seen that yet. It would pay to check this also.
