Question about 2002 Buick LeSabre
This issue is observed in the Car's having Faulty Thermostat. But according to you, the thermostat is new but the new one can be defective. But OK, let us take it as fine. If the Thermostat is all right then the Problem may be in the Coolant. Check that the Coolant is correctly reaching the Heater Core. If no, this issue can be observed. Also check that the Coolant is not dirty of the Heater Core is dirty or clogged. Also check the HVAC which is the Heater Control Valve. It can be the point of failure. And also the main thing, are the Fans working ??
Kindly check the above locations and reply me if the issue is not resolved. Also the issue can't be resolved by oneself. You have to get a Certified Technician for it.
Thank you Sir, Have a nice day.
