check heater control valve

if you mean no heat from the heater system then the problem is nothing to do with the engine and cooling system, the problem will be either with the heater core being plugged up or the control valve in one of the core hoses being stuck or not being opened by the control panel in the dash, or the controle panel not opening up the right door in the heater box assembly to let heat from the heater core box in
etc
it can be very difficult to diagnose the cause and where at exactly in the system
first thing i would do is feel both the heater core hoses and see if both feel the same temperature, if not then theres a problem with the core or the control valve in the hose, or the control panel
good luck

sounds like the controls might be broke. some use a series of vacuum hoses to open and close a trap door inside the unit. u may have a cable off somewhere.also, heater cores do get clogged. they are like little radiators. u can take off the hoses and back flush the heater core to fix this problem. make sure u put the hoses back on right. these are found on the fire-wall.good luck.
