    98 Dodge Ram 2500. Heat comes on, but luke warm.

    Shop says its probably the temp door, but how hard is it to get to that door?

    They say they have to take the entire dash board out.

    Where do I look to get to it the temp door to see if its broken?

Hi my name is Allen!

If both sides of heater core hoses or to hot to hold on too then your heater is OK, but if one is to hot too hold on to and the other is just warm and you can keep holding it then you have a restricted heater core.

NOTE: If both or to hot too hold, then you have a door problem. If you change the temp door and air flow feel the same, then you could have either a bad motor or a broken door.

NOTE: We have seen a lot of broken doors on this year model, if you can reach the motor for the temp door and take it off. Then you can turn the lever and if it keeps turning you have a broken door.

are you talking about your heater core for heat in the truck ? is there a valve in the heater hose that you have to open to get the hoses hot to the core this is under the hood , follow the hoses , could be clogged core , does it over heat , or get up to temp should be about 190 normal temp for most motors why did you change these parts anyhow , did you use the radiator fix bars leak stuff that you put in , bars leak , if so you may have clogged your core , take the hoses off the core and blow it out ,pain in the but you went this far , ck for that valve to open

Possible, with rad cap off, let vehicle idle until coolant fan comes on then shut vehicle off for 30 minute cool down. Top up rad, install cap and drive and recheck heater operation and any overheating.

You probably have a plugged heater core. If one hose is hot, and other one is quite a bit cooler or cooler, then you have a problem with flow through heater core. Try flushing it. I hope that will help.

Good Luck!

Lowheater (temp) output


It could be your blend door or not enough flow through your heater core. Try removing the heater hoses at the heater core and flushing both directions with a garden hose!

All i get from my heater is heat i cant turn the ac on, and when i turn off the heater it still blows hot air


Sounds like a stuck heater core valve. Find heater core valve. Under hood, find the two heater core hoses going into firewall. One of the hoses has a valve. Operate temperature control (full heat, then full cold) check that valve changes position. If not either replace valve or control system failure. Also, when temperature control in cold position, one hose should feel hot and the other cold. Temp fix: disable valve to close no heat or on heat.
