my 04 Pilot's front heating vents only blow out cold air but the rear vents blow out hot air what should i do.

 

Check the hot water valve under the hood by the firewall and make sure it's moving with the temp control ****. If it is moving check both heater hoses to see if they are hot. If they are both hot then you have a blend door problem in the dashboard. If one is hot and the other is just warm or cold then you have a broken blend door. If it is not moving with the temp ****, the cable slipped off or once again the blend door is acting up.

 

Thanks for the info but do you have a DIY thread that I can use. thanks
