Is the engine running?

Like he said... you need to know if you're getting hot coolant to the hear core. Feel the hoses. If both are hot then you should have heat. If one is hot and one is cold then something isn't flowing correctly. If both are cold something is stopping the coolant up stream.

In for info on the heater core flush.My heater does not get very warm either.I'm losing a little coolant every week out of my overflow too. No visible leaks, no white smoke, oil looks good.
