Hi guys, I have a 2004 Accord Ex V6 dual climate control and I am not getting any heat. The temperture gauge is showing normal. The blower motor is working. The upper& lower rad hoses are hot to thouch and the lower heater core intake hose ishot, the heater valve is working ok...but the top return heater hose is cold to thouch.So the hot cooling is not circulating through the heater core. Any suggestion would be appreciated.

Ok Wayne, I have don't everything you said. Now will you help?

 

There should be a flow valve just before the heater core that opens/closes to allow the exchange, this may be hanging up, trace your lines into the heater core and look for it, make sure it's still connected etc. Is the car still under warranty by chance?

 

man...i understand your frustration...but give these new people a break...he had the model yr engine in his post....christ...

 

On accords, the 2-door and 4-door models are basically different cars. I couldn't tell you how much time I've spent looking to help people and had it turn out to be the wrong model.

How do you know that the valve is working properly? If it is, it sounds like there's something in your heater core .... bad news. Have you ever used radiator sealer? That stuff can gel and cake onto the tubes and cause restrictions. Since you have a total blockage, I'd suspect the valve.

PS - Thanks for the signature.

they might...but that's a fact of growing up in the midwest...part of the dialect, even the die hard catholics.

 

I got heat, thanks guys, I replace the valve and now it's working fine. Much appreciated

 

Hey guys, i have a similar problme on my 2004 accord with dual climat. I get heat when teh car is driving, but when im at idle the air goes cold. When i rev the engine to around 2 - 3k rpm i start getting hot air again? Any suggestions?

 

you will get more replies if you start your own thread, that way people will see it. Also, post it in the General Tech Help section, the DIY request section is not really for asking for help, although its not really strictly enforced.
