The wire from the battery to solenoid is corroded & should be replaced.
it should be on the bottom engine side of the radiator opposite the lower hose. you may need to remove the plastic sheilding from the bottom to get to it
The thermostat on a 1992 LeSabre should be inside of the top radiator hose inlet. You can easily change it by removing the top hose and water inlet.
