Normally the issue with this the motor itself however, if could be a power feed issue so we need to check these things out before we replace the motor. Here is a guide that will help with this:

I am attaching the wiring diagram below so that we can check voltage and find out if the blower is even getting voltage to turn on. If it is then the blower is the issue.

If it is not then we need to track it back through the system to find where the voltage is. Here is a guide that will help with this testing:

If it turns out to be the motor then here is a guide that will help with step by step instructions on replacing it:
