How do I know if my thermostat is stuck open?
Symptoms of a bad thermostat
Thermostat stuck open: When the thermostat is stuck open, the engine temperature drops below normal when driving, especially on the highway in cold weather. A stuck-open thermostat can also cause lack of heat from the heating system. The Check Engine light may come on too.
Why we should not use fan when AC is on?
