If the floor outlet air temperature is too low, Check the engine coolant temperature specifications. Both of the heater hoses should be hot to the touch. The coolant return heater hose should be slightly cooler than the coolant supply heater hose. If the return hose is much cooler than the supply hose, locate and repair the engine coolant flow obstruction in the cooling system. OBSTRUCTED COOLANT FLOW: Faulty water pump. Faulty thermostat. Pinched or kinked heater hoses. Improper heater hose routing. Plugged heater hoses or supply and return ports at the cooling system connections. A plugged heater core. If proper coolant flow through the cooling system is verified, and heater outlet air temperature is still low, a mechanical problem may exist. MECHANICAL PROBLEMS: Possible locations or causes of insufficient heat: An obstructed cowl air intake. Obstructed heater system outlets. A faulty, obstructed or improperly installed blend-air door or actuator. A faulty blower system. A faulty heater-A/C control. TEMPERATURE CONTROL : If the heater outlet air temperature cannot be adjusted with the temperature control knob on the heater-A/C control panel, the following could require service: A faulty heater-A/C control. Faulty blend door actuator. A faulty, obstructed or improperly installed blend-air door. An obstructed cowl air intake. The engine cooling system.
