First is your tempature gauge reading normal? If so, I would have someone check the thermostat. If it is constantly cold means it might be stuck open where as the coolant is ciculating through the radiator. The engine thermostat, on start up, circulates the coolant through the engine and heater core. Once the engine reaches operating temp the thermostat opens to ciculate the engine coolant through the radiator, so if it is constantly circulating through the radiator it takes a long time to warm up. At colder areas it may never warm up. Vise versa if you have plenty of fluid and its overheating the thermostat is stuck closed, or one possible reason anyway.
However if you havent had the fluid changed in awhile and the thermostat is working properly I would have someone check the flow through the heater core, it could be plugged.

I'm new to the forum, my name is GM58 and I experienced a very similar condition where my temperature guage would take a long time before it would move and then it would only go to a quarter. I replaced the thermostat housing but the condition continued. I did some research and spoke with some technicians at my local Chevy dealership. They recommended that I replace the coolant reservoir cap with a GM cap, problem solved. I now have full operating temperature and plenty of heat.
