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

KEEP US POSTED
