I am getting a lot of exhust smell in the cabin coming through the heater vents. It is much worse in stop and go traffic than on the highway. Defrost seems to be worse than low or mixed vent. How do I trouble shoot this problem?
AT 1ST, IF IT'S SLOW---EVIDENCE MAY BE HARD TO DETECT
IF IT GETS A LITTLE WORSE---YOU MAY SEE "COOLANT" DRIPPING OUT OF THE A/C DRAIN HOLE (FIREWALL IN FRONT OF THE HEATER) A WHITE PAPER TOWEL LAID ON THE FLOOR BENEATH IT MAY SHOW THE COOLANT COLOR
THE FIREWALL BRINGS ME TO ONE OTHER EZer TO FIX POSSIBILITY---SOMETIMES WHERE THE HEATER HOSES CLAMP TO THE HEATER CORETHE CLAMPS ARE TOO BIG OR NOT TIGHT ENOUGH. RADIATOR JUICE MAY SLIP OUT AT THE CONNECTION AND DRIP INTO THE HEATER BOX
