My Dodge Ram 1500 has no heat output. I flushed heater core with distilled water, then filled with proper coolant and still not heat. Any tips?

 

Feel the heater hoses where they go into the firewall. They feed coolant in and out of the heater core. If they are both hot, then you have an issue with your venting.

 

More info on what your situation would be helpful. You're not getting heat, but what are you getting? Cool air, no air, hear fan running but nothing coming out vents?
Have you done any work on the dash area, like install a stereo?

 

yes both heater hoses are hot

 

yes i am getting VERY cold air and it does flow out of all vents, just no hot air. Nothing makes an unusual noise.

 

Recirculating Door?

 

The recirculating door seems to be functioning properly

 

the previous owner did install a speaker system and a new head unit

 

EDIT: Did you pull the glove box to watch the recirculating door?
Did you get all the air out when you flushed everything?

 

Good comments so far and I rec following as next steps;
- heater core could have air pockets. One way to tell if there are air pockets is to listen for a gurgling noise in the heater core. Do this with engine running and at operating temp.
- HVAC controls may not have been re-connected correctly during aftermarket radio install. You would need to pop the center dash bezel and check the connections. Or could be bad rheostat.
- Blend door. I rec you research blend door problems, if you haven't already, and see if you have same symptoms.

I'm leaning toward heater core air pockets (or leak), but I think you would have a temp problem with your engine if this was the case, so I'm not certain. It sounds like air is being directed properly, it's just not warm, and that makes me think heater core problem or switch.
