Welcome to the forums.

Double trouble.
Did you try the system without the thermostat connected ?
There are several different fan boards so you need to post the part number for the one you changed.

Typically the blower is controlled by the G wire coming from the thermostat or the purple wire from the heat strips if you a heat pump system or electric heat.

Very unlikely the new relay's contacts have failed in the closed condition causing the fan to run when relay is de-energized. Your problem is in something else you changed.

Posting a picture of the new relay (as wired) may be of assistance.
It might be as easy as moving a wire.

Goodman ARUF A/C Heater will not run
