No periods. Your post makes no sense.

what makes you say that

what makes you think the speed of the motor has changed? is the airflow lower than when you put it in?

I have seen motors work and not work but not miraculously drop in speed unless we are talking about some fancy variable speed ECM kinda stuff.

blower speed

Bet its an X13 motor. If so, change immediately. Even if its not the motor it will be soon.
