Oldsmobile/Buick Repair: heater, olds achieva, achieva

Question
I have a 1992 Olds Achieva.  On the cold days here in Minnesota it makes a grinding sound, now today, it also has an odor.  Is the cold making it freeze up, or do you think it is going bad?  On days above freezing it does not do that, only when I REALLY need the thing.  Thanks

Answer
