I just had to do this on my ne Prelude. First, check the valve that lets coolant into the heatercore by the firewall (mine was only open half way, I pushed it open by hand). Next, backflush the heater core. There is probably tons of blockage in there if no one has ever worked on it. You may have a clogged hose from the thermostat housing to the heater core valve, thats where mine was really bad. Hope this can help. I learned the hard way by ripping my whole car apart.
