I own a 81 280zx.
the heater, along with the defroster doesn't work.
I know nothing about these units. I thought maybe
some of my Fellow Z Brothers out there may know.
Air comes out of the vents, and there's coolant going
in and out of the firewall. But no Heat. Just plain air.
and if you do know what it is, how much is it going to
cost me? (Not taking it to a Auto Store to do it)
thanks for any comments

You most likely have a vacumn leak, The heater/ac needs vacumn to work properly.

If it has climate control check the vacumn line as the canister in the engine comparment. each line has a separte color and most go as indicated in the shop manual.

When was the last time you changed the thermostat?

4 weeks ago the Thermostat hoursing was leaking on the block (It was just a gasket)
But, I changed the thermostat at the same time.
