Default Heater defrost blowing cold air

So could this be the heater hose and/or system clogged or is there another dash door malfunction. When i go from AC to heat, one door is redirecting the air from the front dash to the windshield, just no warm air in heat or defrost.

DO you have hot air, at any time and from any opening? Floor, Dash vents, etc?

Blows cold air on what ever vents are selected. No hot or warm air at any vent.

there is a chance that the heater core is blocked

one way to tell is to set your heater to all the high settings & drive a few miles
Then find the 2 heater hoses under the hood, both hoses should be hot or at least fairly warm.
If only one hose is hot & the other one is cool, the hot one is the heater supply hose & the other is the return hose.

If only one hose is hot, you may have a gunk build up in the heater core, OR you may have something wrong with the Heater Control Valve, like a broken spring or jammed lever

some images of heater control valves
https://www.google.com/search?q=2003...UICCgD#imgrc=_

If the valve is good, you may need to try to push water or air backwards through the heater core, there is a youtube video that shows how to do it, don't be wearing good clothes & wear eye protection



in the comments below the video, it reads

Heater problems in the winter suck. But with a little diagnosis you can usually figure out the problem. Heater cores can get clogged from time to time and this video presents a solution to that problem should you have it. BTW, the product used in the video was CLR. If you KNOW you have a clogged heater core this procedure is a good thing to try to help fix the problem. However, if you are having heating problems I would suggest you check for air in the cooling system first before performing this procedure. The #1 cause of heating problems is actually air in the cooling system. More information on how to deal with HVAC issues can be found in this article I wrote.

Hey thansks, seems like i remember being told you should run your heater a few times during the summer to lessing the chance of it clogging up. Thanks again.
