I changed the fan wheel on my furnace and now it starts but it seems like it doesn't blow air! I cleaned the coil with a proper spray cause I thought that maybe it wasn't allowing the air to flow but it still won't blow air and the motor is working and spinning!

Is the fan mounted on the motor shaft or is the fan belt driven?

Wow I am so stupid!! I put the motor on the left side of the housing and it should have been on the right side!! So I just switched it and surprise surprise it work perfect!! Sorry for wasting your time!!

Congrats. Don't worry, I've done worse things.
