    More info would be nice.

    Make and model?

    Is there any air coming out?

    Is the engine getting hot?

    It is really hard to guess all this.

    Make sure both heater hoses are hot where they connect to the heater core at the passenger side firewall. If not, the heater core is plugged up.

    check your coolant, very easy fix, my car leaks coolant, so i know its low when the heater stops getting hot:-)

    Blowing cold air--- low coolant level

    No air volume--- vacuum line poped off or is cracked
