Do the cooling fans work?
An air pocket usually blocks coolant flow through the heater core, and thus no heat from it....air pockets are caused by leaks...sometimes the leak is so small, a dye and black light are needed to find it.........

i did the dye test no leaks I went for a ride today 10 miles down freeway it stayed right in middle all the way there. came home on the back roads (i was only stopped for 20 minutes) 2 miles down the road it was in the red. so i stop for 30 min while i was stopped i checked hoses top and bottom were hot bottom not as hot as top. heater hoses i think its the inlet on right side was kinda hot other one was much cooler. so im going to try and back blow the heater core just for fun.
