My 2004 honda odyssey heater wont heat, neither the front or the back! I changed the thermostat, I purged the system, I changed the cabin air filter and still no heat, the door that changes the settings from hot to cold works fine too, and also the fans start working too soon. Any ideas on what it could be?

Check to see if the hose going out of the heater core is hot. If not, you have a plugged heater core.

IF you have hot coolant going through the heater core, then the blend door has to be the problem.
