HELP! Obscure HVAC issues

[jsullly]

2014 Equinox, 2.4 FWD. I had replaced the: thermostat, radiator, coolant (obviously), purged the air & the climate control module behind the radio/climate controls, the blower motor resistor, and the blend door actuator. SOMEHOW, I'm still unable to get heat inside the cabin & at running temperature the heater core hoses are sitting pretty hot as I can't grab onto them for more than a second, they're hot to the touch. I'm not leaking coolant & using DEXCOOL only. Its 22 degrees in Detroit currently & am struggling to find the solution to this, can anyone either relate or point me towards a potential solution? (I've got the manual HVAC controls/system not the automatic)

It is possible to have a brand new thermostat be faulty. Can you see the temperature gauge change as the thermostat opens ?

This is true.I'm going attempt to swap it out again; I noticed that even after being on for hours, my temp stays at the 7 o'clock position, never fully reaching the half way mark. I've been checking the differences in temp/pressures between the upper and lower rad hoses by feel & if the lower hose gets gradually warm that means the thermostat opened?

I'm really late to the scene; I don't see posts until an email with links arrives...

If both heater hoses are hot, that indicates coolant flow through the heater core does it not?
You didn't mention anything about the blower. If no air flow, you won't be getting much heat from the heater core.
