I’m glad It helped. I’m also somewhat relieved to know I am not the only one stuff like this happens to lolThis second paragraph was a LIFE SAVER! Replaced my A/C Evaporator Core, Heater Core, Blower Motor, Blower Motor Resistor, and Blower Motor Wheel. The new Blower Motor came with no connector, one black wire and one orange wire. So naturally, I spliced the wires together, color for color. When reinstalled and all back together, no air was blowing through the vents. I checked everything but could not find the problem. So I pulled the HVAC box again to check all components but to no avail. Once put back together again, still no air from vents. Came across this post while searching for a solution. Read about the orange and black wires needing to be wired "in reverse." I knew right then and there that that would solve the problem. Amazingly that was it - problem solved!!! Thank you, MUSTANGGARAGE!!!
