heat not working
 

I just bought a 1990 N/a. When I test drove it last week, the heat worked fine. But now all it does is blow cold air, no matter what temp the climate control is set at. Since it worked just a week ago, I'm guessing it might be less likely to be a mechanical problem and more likely that some of the climate control settings are screwed up. Any ideas?

My heat doesn't work unless I put it on Auto/Econ/High or Low Fan and then the desired temperature. My Z is also a 1990 N/A.

Check your radiator fluid, I had the same problem and I had a harline crack in my radiator line so my radiator fluid kept leaking out. Got the line replaced and heat works fine. Hairline crack is so hard to find though unless you put it under pressure.
