Certainly. If the engine coolant is flowing freely into the radiator, it will remain quite cool and the coolant that circulates into the heater core will never warm up. The thermostat blocks the coolant from entering into the radiator if the temperature is below the set level on the thermostat. Usually 185, or 195 degrees F. Engines don't run as efficiently at the lower temperature either, so if the thermostat isn't working right, replace it.

Sticking thermostat could cause this. If the thermostat is stuck open, it never gives the engine a chance to fully heat the coolant. Follow the top radiator hose to the engine, remove the hose and remove what it hooks to and there's your thermostat.
