Whats the heat light mean on a 1989 Mazda familia?
I have a 1986 Mazda familia/323, whose heat light is on. I was
told it was the catalytic converter that has collapsed. Infact it
had and I dismantled the exhaust system and found bits of the
catalytic in the muffler. I dismantled the rest of the system and
found where the converter was. I removed all the catalytic and
reassembled the exhaust. Guess what? the light is still on! So I am
still ssearching for more info.
