Cold Heater Hose and No Heat

[batmmannn]

I am wondering if no heat and cold heater hose that runs into the firewall on the passenger side could be related to any overheating issues.

I just burped my system again but this time turned the heat on high and got a couple of small bubbles out, then nothing.

I notice I have no heat and the heater hose was cool to the touch. Bad heater valve?

Any thoughts on this would be greatly appreciated, would this mean a blocked heater core? Something not working?

I found this thread but I am not sure what hose they are referring to. Is it the bottom hose that is already on the VSV that gets attached to the top of the VSV? It is not very specific. They say the bottom hose that goes to the manifold. Still not clear on this.
