the heater control valve is not opening all the way.
look under the hood on one on the heater hoses .
you should find a vaccum controled heater hose valve.
make sure your not low on coolant also.
also make sure none of the heater hoses are pinched off.

One thing to consider is your thermostat and water pump. If somehow, your thermostat is stuck open, your engine won't get up to temperature. Also, a bad waterpump won't move coolant thru the heater core. Both of these situations should show up on your engine temperature, making it hot or cold...but sometimes they don't show up if your driving pattern doesn't tax the engine..My daughter's car had a bad electric cooling fan , and never was a problem, unless she was stuck in traffic...

1st check the coolant level. If it's low, what you describe will happen. If level is ok, let me know, and include info on engine temp gauge--how long to warm up, is gauge at warm up low temp range, normal, or hot?
