I have a 2001 MDX that I bought in June of this year. I have had the hardest time figuring out why I have no heat. The blower motor works it just blows cold air. I have replaced the thermostat. I have flushed the heater core. The valve on the firewall is functioning. If all my coolant is flowing properly what should I check next?

 

I bought an 2002 in February and having the same problem only my heater control valve was broke. So I replaced it and flushed my core. I now have tepid air instead of ice cold when set to 90 degrees. I'm trying to find info on an inside temperature sensor but everything I search just mentions coolant temperature sensor or outside/ambient temp sensor. Have you had any luck yet fixing yours?

 

Hey I currently have a 03 mDX which is throwing only Luke warm air, checked everything and seems to be fine. Have u guys had any luck on ur issues?
