My car stopped producing heat a few months ago. The thermostat was replaced first, still no heat. The heater core was flushed, no heat. I also replaced the temp sensor, blower motor and water pump and finally the heater core. Still no heat! At idle the cabin gets warm, when increasing Rpm's the air becomes cold again. I pulled the dash apart and got to the blend doors. I moved them manually and they are not stuck or broken. Any solutions?

What do the heater doors look like? Are they shiny with holes in them?

Are both heater core hoses hot to the touch?

Both lines are hot to touch. Yes the heater doors look like that.

The foam is missing from the doors... that is why you are not able to direct the cold air past the heater core to get warm.

The doors need to be re-lined with foam.

Watch my Eurovan heater core video:

At 8:05 you will see the same doors with no foam.

Fix the doors and you will have heat again!

Sorry for not getting back to you. The foam is actually not the problem. Any other ideas?

Then this is something I can't guess over the internet. I would have to have the car in my hands.

Manual or climatronic heater panel?

If climatronic, run basic settings to reset the motors / flaps.
