In this picture, below where it reads 240vac, 12fla........
There is a heavy yellow wire connected to what looks to say Blower. My guess is that this is the "high" on the fan motor. Try and see on the schematic which wire would be the "medium" speed and connect it to where this yellow wire is. I have seen before where the high speed will burn out but when connected to one of the lower speeds not used it will work and get you out of a pinch
