Post a picture of any diagrams on your air handler.
Trace your 3 fan wires to the other end and post what they connect to (sequencer m1, fan relay,common?

If you remove the 2 quarter inch screws holding the panel, separate the wires to your fan relay and post a picture.

Unless you are talking about heat mode, it may be a stat problem. The stat G terminal should be energized for fan ON or cooling demand. It appears to be blue at the relay but I can't tell what it wire nuts to.

I'd expect it to wire much the same as this diagram (substituding your yellow for their violet)

If this is the case, yellow is common and black and red are 2 speeds. Further tracing is necessary to confirn this though.

"Tip of the Day" Remember to remove power first.
