[Help] My Ender 3 isn't powering the extruder motor. Do I need a new motherboard? (self.3dprinting)

The extruder suddenly stopped working after I cleared a jam that caused it to grind.

I tried every combination of motor and cable to trace the problem. It seems the only fault is the extruder's motherboard connector.
The motor is functional. I connected it to the XYZ motor cables and it spins on every one.
Nothing happened when I tried plugging the other axis cables into the extruder port on the motherboard.
Finally, I am comfortable using a multimeter and soldering iron, but don't have immediate access to them.

I really appreciate any advice on this because I miss printing!

I've got an Ender 3 pro motherboard (not silent steppers) that you can have for shipping costs if you determine that's the issue. If you do, pn me your zip code and I'll let you know how much it would be.

~~I would test the ribbon cable to the extruder before replacing the mobo. That's a more common failure. Plug one of the other stepper cables into the extruder port and see if it moves. If it does, the mobo is good and the cable Is bad. ~~

Edit: I see you've done that.

You might still try reflashing the board just to make sure it isn't a software issue. But if you need one let me know.
