I have a 02 ford ranger 4cyl 2.3L and there is a 1/2" tube coming out of my firewall by the heater core that is leaking coolant

I think you're right. It looks like the drain tube below the control valve is wet. There used to be a 4" rubber hose hanging down from it to help keep debris and cold air out.
