This exact thing happened to me recently with my 1990 300zx 2 seater, the motors inside the dash will not work anymore and I can't get it to change to heat, it simply blows out cold air all the time no matter what settings I put it on. I took it to Nissan and they simply turned the motors or vents in the direction needed for heat and charged me around $400 just to change some corroded plugs and not replace anything in the heat, just get it blowing out hot air.

Well I was messing with the temp gauge and I switched it to ac and now when I switch back to heat, the motors stay on AC so I am left with the same damn problem again.

Is there anyway to temporarily move the vents back again to the heat position? Is it so hard you can't do it yourself? I am not that mechanical but I am willing to try anything.

"they simply turned the motors or vents in the direction needed for heat"
Could you please give me more detail? I don't understand the turned part? Also what year is your Z?

It is a 1990. And all I said there was that I know Nissan didn't fix the problem when I brought it in to them, I believe they simply manually adjusted the vent direction so that the hot air blew out through the front and top vents.
