A few days ago I switched my fan speed and had no issues turning the system back on. Yesterday when I switched it back from low to medium the breaker on the blower tripped and I can't reset it. House breaker is fine and there are no blown fuses. I can't find a reset switch either but ask for any other ideas or thoughts?

You may have accidentally exchanged the wrong wires... recheck your work. About the only thing you could have done wrong is exchanged the common wire (usually white) for a speed tap. Check the schematic and verify all colors are landed properly.

Otherwise, the motor may have failed... big coincidence but always possible.
