Default 98 ram 1500 5.2 NO HEAT

hello I have a 98 ram 1500 5.2 with no heat. The heater core is new, new water pump, thermostat, etc. What else could cause little to no heat to come out of vents?

Temp door cable hooked up?

Air pockets in the heater core. <- This is the most common problem......

Mine; the foam seal on the blend door had stuck the door to the box (years of no use).
Much cycling of the control finally broke it loose... and I got a shower of foam crumbs out of the vents.
