Roof ac fan issue

[GTMADNS]

Last summer had the blower motor seized up. I bought a new blower exact 3 speed blower same company and part number. Installed it and blower has 1 speed. I tried moving the wires around thinking maybe motor was wired incorrect accounting to their diagram. I just bought a new Capitor thinking maybe that got burnt out when motor seized up. Same thing 1 speed. Any ideas ?
This is a dometic a/c roof top unit on a 15 coachman sport coach.
Thanks in advance

It's possible that when the motor seized it may have caused damage to the switch assembly?

I believe it’s medium

What speed is it running on, high, medium or low?
