no i didnt refill under vaccum just trying to figure out why there isfull heat on the passeger side and not the drivers side is there two heater cores? the ford dealer i talked to yesterday said that they would need to pull the full dash out and pull the heaterbox out as well. i wasnt sure how many acctuators there are on the heater box. the diagram i found showed 2 that control the heat heat and you can see them both working. I put a bore camera down the vent and can see all the doors moving when the controls are turned

There was another guy on here this week with the same problem after flushing his coolant. It was mentioned there are separate heater cores for the split heat, you might have air in one. Drive it awhile and see if it burps. I did. It refill mine under vacuum and after a thousand miles or so I had to add a couple quarts more distilled water.

I'm having the same issue. I applied vacuum to my coolant system and saw no change. Good heat on passenger side, none on driver. I'm not sure either.
I've driven about 150 miles since the coolant flush, no changes in level.

I'm not sure. In the next week or so in going to drain the radiator and then pull vacuum and fill again to see if that helps.

I had a Chevy truck the battery went dead and did all kinds of things to the heating / cooling in cab.
Would of never thought that this was the problem had to disconnect the battery turn key on and reconnect battery.
Something like that worked fine after that.
Running battery dead does funny things.

What did they charge you for the core replacement? I had a tech tell me he could get it done in about 3 hours but the book calls for 12 so that's what they will charge.
My buddy works at a shop and has a flushing machine, I may try that first...
