I have a 1995 ford f150. I stripped the heater core it's not blocked, fluid is flowing through both hoses very hot. When i stripped the box in behind the glovebox the heater core is very hot but the top left hand corner is blowing through cold air cant figure it out open to suggestions. Bit of a pain in the rear scraping ice from the inside of the window these mornings... Somebody help please

No I stripped out the glove compartment and took the plastic casing off the heater core. The entire core was very hot. No air was passing through, it's not blocked because I took it out. At the top left hand corner cold air was blowing through. This was the only place any air was comming through and it was cold But the rest of the core was hot ??????????? The truck has an a/c if that has anything to do with it.
I would guess that you have a trapped air pocket there. Fluid is still moving through the core but for some reason you have air trapped there and since this is where the air is blowing through it, it does not heat up.
