I would at least check the thermostat. If you do replace it, point the spring to the block. After that, Try warming the Vehicle, then carefully feel the heater hoses, are they both hot? If one is cooler than the other, you may need s replacement job on the heater core. Also if the system has a heat control valve on the heater hose, make sure it is working!
