Well as long as there's hot coolant flowing through the heater, you should be getting hot heat. That means that something is blocking the flow, and there are only two things I can think of that would do that. One is the thermostat, and the other is the heater hose valve on the firewall. There are two cables going to that valve that are connected to the temp knob. See if that valve moves when you change the temp. Go to full cold, and look at the valve. Then go to full hot and check again to see if it moved. If it's not working you can manually open it.

If it is operating properly replace the thermostat. Get a new one through Honda, they're cheap enough that you won't save much going to Autozone or any similar store.

I guess you could also have a failed water pump, but I don't hear of that happening too often. You'd probably also have overheating issues if that were the case.

i had a similar problem with that valve. get the car warmed up, and it can take a while when its freezing cold outside. turn the heat on, move the valve one direction and see if starts to blow warm air. If not turn the valve the other way and check again.

If even a little bit of warm air is coming out once you are moving and the car is heated up, It could just be your blower motor. If thats the case it is a pretty cheap fix, and I believe you can get to it without even pulling the dash, it is kind of behind the glove box.

Check for the switch/lever underneath the dash. It should be a white level or roughly 2 inches that one of the two cables goes to. The main cable hold often breaks here, and the valve no longer gets turned. Try switching it and then playing around with your heat. That was the problem with my heater, and numerous others I've talked to.

this is most likely your problem. its the air mixture flap.

crawl underneath, behind the center console and look straight up. youll see the white lever. the cable probably came loose. it should be obvious what to fix.
