Hot then COLD
This morning my maxima was at proper operating temp. when I turned on the heat at 85 degrees. The air came out hot for the first few seconds then got cold??? Could this be a sign of trouble with the heater core?? Today was the first time this happened.

Check the obvious first.
Coolant level ??
Thermostat - Does your temp gauge go up and down or stay steady?
Heater hoses kinked? Have you done anything under the hood lately?
I believe there is a heater core water valve, this may be sticking partially closed, not letting enough water flow through your heater core.
Do you have auto climate control or manual?
A good cooling system flush, including the heater core could get things flowing nicely again.

Coolant level is fine.

Thermostat stays steady in the middle, after warming up of course.

I'll look into that.

I have a automatic climate control.

Wait...... Thermostat?
My needle gauge during warm-up goes up and down erratically whenever I am driving it in the first 15 minutes or so.
I usually warm up my car for about 5-10 minutes before driving it, and it is usually at about just a needle above the "C". Then, when I start driving it, it sometimes goes up and down when there is a strong wind or bump in the road (or sometimes nothing at all).
However, once it's fully warmed up, it's fine. The needle will stay there nonetheless. How do you check up the thermostat?
Thanks!

Problem Solved
First, thanks for all your help 
I was driving in the city yesterday when my temp needle 3 quarters of the way up. I was like WTF??? So I pulled over and I had no coolant. ARGH! so I bought some distilled water and poured it in both the resevour and directly through the radiator cap. The radiator was empty. A soon As I got back to Brooklyn I bought some water wetter and poured that it. All my problems are gone. I'm so happy now.
The reason I had no coolant, I have a leak in one of the hoses. I will replace that hose this summer sometime. It only leaks under hard acceleration.
Again thanks for all your help.
