It's a harbor breeze fan. Have separate switches for light/fan.

Wired as follows:

• White to white.
• Black to black.
• Red to blue.

2 green from fan bracket and rod to copper ground.

No sign of light but fan works.

Any help is appreciated!

Your wiring is correct for a fan/light combination.Since you know your fan works with the switch, take the black wire from the switch and connect it to the blue wire from the fan. If the light works then you have no power in the other switch. If the light does not work then the problem is in the fan/light
