Default No Heat anymore

We purchased our 2004 Murano brand new and at first had no real problems, but then a few times the heater would not work. The dealor replaced the radiator cap a few times and that fixed it for a short periods, usually until winter was over, then in next winter we would do it again. It never did seem to blow real hot air like my Chevy truck, but is was always enough to keep the kids warm until this year. This year and last year it has gotten worse. Our warrenty is no longer and we have no heat except when we run at 3500 RPM or greater, and that is hard on the car and gas mileage. With two small kids and weather well below zero we have not been able to drive it all winter. Our local mechanic can't figure it out either and he has spent hours on the phone with Nissan dealors. Our mechanic has replaced the thermistat, a valve or two in the heating/cooling system, flushed and reflushed and bled and rebled the lines many times as specified. The heater core puts out good heat, but it does not get into the car unless we drive at those high RPM's. Our local Mechanic has gone through everything he and I could think of, we still get no heat. HELP anyone!!!!!???????
