Heater does not blow warm air for a long time, sometimes 30 -45 minutes after starting to drive. Engine temperature gauge goes to normal level and doesn't overheat, no weird smell or smoke or anything. Will eventually start to blow warmish air after have been driving around for a while. Is this the thermostat or is the heater core going out. No leaks in or under the car.
