Blower not working for air but does for heat

I have a Central Electricbrand furnace for modular Home model eb20b. The fan blower stopped working. It comes on with heat but not air. I replaced the thermostat and still nothing. The fuses are all on so what's my next step? I just paid to have the outside fan motor ,,blade and capacitor replaced 10 days ago.

Most likely the blower relay needs to be replaced. Google relay 3110-3301.

It is easy to replace the relay.
It would be safer if you turn off the breakers to the air handler as well as the 2 breakers in the air handler.

It looks like that relay is $20.

2 screws and 6 wires.

You are very welcome.

High voltage is present in that unit. Remember to turn off the breakers before replacing the relay.

I usually snap a picture or 2 before replacing parts.

Looking at these diagrams is confusing to me. Where do I start to look? Do I have to remove the fan and motor

The black and white diagram is your component arrangement.

If this air handler is vertically installed in an upflow application, I would expect to remove the top panel and see the fan relay on the top left portion of the control area.

if it is a down flow application the controls would be in the lower portion of the air handler.
