Heater only works, when my foot is on the gas pedal?

CHECK YOUR COOLANT LEVEL (RADIATOR JUICE) IF LOW, REFILL AND CHECK FOR HEATER OPERATION

CHECK ALL CONTROL POSITIONS FOR HEAT OR DEFROST--DOES IT COME OUT HOT, LIKE IT SHOULD IN ANY OF THE POSITIONS?. COLD IN OTHERS?

IF THINGS STILL AIN'T GOOD,

AFTER ENGINE HAS HAD PLENTY OF WARM-UP TIME

GRAB THE UPPER RADIATOR HOSE AND THE HEATER HOSES

WATCH OUT FOR THOSE PESKY MOVING PARTS!

IF THEY FEEL COLD OR BARELY WARM---YOUR THERMOSTAT MAY NEED TO BE REPLACED

IF THEY ARE SO HOT YOU CAN'T COMFORTABLY HOLD ON TO THEM---SOMETHING MAY BE WRONG IN THE HEATER BOX--SUCH AS A BLEND DOOR NOT OPENING
