okay so it has dropped down into the teen's in temperature the past week, so I have been cranking the heat in my car...well trying too!
I have had my 90 z32 for about 3 months now, and the ac works amazing
But the heat not soo much, it's set on 90 but feels like 75 and is not really blowing through my vents.
It's mainly coming from my defrost and floor boards.
I have no problem defrost my windows when set to the according setting.
It's just the auto button...and it won't engage REC sometimes
While driving today I did not let my car warm up all the way, I had droven it previously about 1 hour before.
And within a 15 min drive the engine water temp sensor never left C sometimes it stayed under it :(
Even after a little "getting on it"
But my climate control is reading the temperature outside fine???!!
:gotme
So can anyone suggest to me what is wrong?
I hope and pray it's not a heater core...
thanks alot in advance!

So the blower does come on but it doesnt blow hot air?

First thing i would do is flush and bleed cooling system completely and make sure you have no coolant leaks
