Re: 1981 280ZX Inside door panel window fuzzies
I had these same issues, but I have a '76 280z, so it may differ from the '81. But the concept should be the same.
a) the little fuzzy trim can be replaced. I got mine from blackdragonauto.com
I had to remove the door panel and remove the old trim, since it is attached to it, and used gorilla glue to re-attach the new fuzz trim. The original had rivets, but I don't have a rivet gun. I would imagine the 280zx is somewhat the same, however only you will be able to tell by removing the panel yourself.
b) yes if your expansion valve is not operating correctly, the air will not be cold.
I did a complete stock a/c install on my 280z and everything worked great accept for the valve, which after about 20 seconds of cold air, would frost up at the inlets and the air would cease to be cold. The FSM says that symptom is the cause of a bad valve. So I swapped it out with another old valve and now the air flows cold quite well. Now in the 280, you can access the valve, and the evaporator housing, and can be removed without removing the dash.... according to the FSM. I don't know if it is the same on the 280zx. Check your manual.
c) When I did my system, the car never had a/c from the factory. So everything I bought was used. All lines, compressor, condenser, pulley bracket, evaporator, etc. I bought a new receiver drier. I completely took apart the evaporator housing and cleaned everything inside. Also replaced all of the cruddy foam and insulation.
If I were you and you plan on taking that stuff out, I would just buy a new evaporator and expansion valve.
Hope this helps.
