Depends on what warning light you are asking about.
A thermostat can prevent overheating on the engine, air-conditioning, by signaling such occurences through warning sounds.
The warning lights on a 1998 Pontiac Grand Am mean that the vehicle's computer has detected a problem. This can range from low tire pressure to malfunctions within the engine itself.
Check engine. Is radiator really full? Does the rad. fan come on? Is the fan belt on water pump tight? If these things are ok, you probably need a new thermostat.

Check the temperature sender. not the sensor, the sender. the sender goes from the thermostat to the computer. They have been know to prevent vehicles from running. I second that.
