check your coolant level
Your thermostat is the likely culprit here it is probably stuck closed. Have it checked out.
Low coolant in the system. Defective heater control valve. Clogged heater core.

My Mazda 656 DX 1996 purrs when it's cold. It runs terrible since I moved to South Florida.
that usually means that you turned off the A/C on a higher degree. If it was cold in the morning and you had the A/C on 90 degrees, then turned it off, even when the A/C is off it will still blow out hot air. Vise Versa. If you had it at 65 degrees, turned it off, the air will still blow in cold.
the blower motor has gone bad
this just happend to me is was low on freon/134a or it could be your blend doors are stuck
Because you set it that way
why does ac blow warm air? why does ac blow warm air?
My 2001 Chevy Blazer was blowing cold air when I had the heat on. My husband flushed the line to the heater core and a bunch of junk came out and now my heat works great.
