Try warming the Vehicle, then carefully feel the heater hoses, are they both hot? If one is cooler than the other, You need to flush the core, or a replacement job on the heater core. Also if the system has a heat control valve on the heater hose, make sure it is working!
The other possiblity is the blend door, work the temp knob, and try to observe the door to see if the servo is opening and closing it.
