NHTSA Complaint #10672633 — 2007 NISSAN ALTIMA

I WAS DRIVING AND I HEARD A CLUNK THAT DID NOT SEEM TO AFFECT MY DRIVING ABILITY OR STABILITY OF THE CAR. HOWEVER, LATER THAT DAY WHEN I TURNED ON THE CARS HEAT; IT WOULD BLOW BUT ONLY COLD AIR WAS COMING OUT OF THE VENTS REGARDLESS OF THE TEMPERATURE SETTING OR MODE SETTING. MY MECHANIC REPLACED THE 2 THERMOSTATS BUT THAT DID NOT FIX THE PROBLEM. THIS PROBLEM WAS A SUDDEN ONSET AND WAS NOT GRADUAL IN NATURE. MY MECHANIC SPECULATED THAT THE HEATING COIL BECAME CLOGGED BUT TO REPLACE IT THE COST WOULD BE IN EXCESS OF $900. I'D ALSO THINK THE CLOGGED SYSTEM WOULD HAVE CAUSED A MORE GRADUAL DECLINE IN HEATING FUNCTION. *TR
