Answer
HI TOM,THE ONLY THING I CAN THINK OF IS THERE IS A RELAY THAT IS STICKING OR GETTING POWER FROM SOME SOURCE TURNING THIS RELAY ON AND OFF. YOU GOT TO FIND WHERE THIS CLICKING IS FROM BEFORE I CAN HELP YOU ANY FURTHER..UNLESS THIS CLICKING IS A BLEND DOOR IN THE HEATER OR A/C SYSTEM AND THE DOOR ACTUATOR IS STRIPPED MAKING THIS CLICKING SOUND TRYING TO MOVE THE DOOR ONE WAY OR THE OTHER...IF YOU CAN NOT FIND THIS CLICKING FEEL ALONG SIDE THE HEATER OR A/C DUCT WORK UNDER THE DASH TO SEE IF YOU CAN FEEL IT AT THIS POINT..IF SO THE DUCT WORK WILL NEED TO COME OUT OF THE DASH TO REPLACE THIS ACTUATOR THAT IS STRIPPED. THERE IS A PLASTIC GEAR TOOTH THAT DO STRIP OUT FROM TIME TO TIME.  THE CLICKING NOISE IS THE TOOTH TRYING TO GET PAST THE STRIPPED GEAR..BUT SEE IF YOU CAN LOCATE WHERE THE CLICK IS COMING FROM AND GET BACK TO ME..GOOD LUCK TO YOU TOM..
