Goodman evap. fan not blowing on cool

I have a goodman air handler/furnace, and the fan blows in heat mode, but does not in cool mode, found the solid state relay to be iffy, so I bought a new board of the correct type, changed it out, made no difference, anyone have any idea?

Welcome to the forums.

Does the blower run in FAN ON mode ?
If not...... you'll need to see if the G terminal is getting 24vAC when in COOL or FAN ON mode.

yes, I discovered after reading PJ's message that I inadvertently knock the wire to the thermostat loose, the green one, reconnected it, everything works as it should, Thanks PJ for leading me to the solution.
