After a car had being lying up for a while(95 jdm itr) i started and drove it and after the temp settled at its usual spot i noticed the heater wasnt working??
No hot air just cold.

coolant levels are ok, Car is not overheating, Fan comes in on time as usual and basically everything seems fine and the car is being used daily??

Would this be a faulty/stuck thermostat

Any help appreciated
