I understand you are having blower issues. Can I get more information such as furnace make and full model number? What checks have you done yourself so far?
Does the blower wheel turn freely if you reach in and spin it with power off?
Is this a standard blower or ECM?
It is a different kind of blower, slightly larger in size than a standard blower and it has smaller wires.
If it's a standard blower, it is either a bad board or a bad motor and is confirmed by measuring voltage
A picture would help me determine type of blower you have if you could upload one.
That looks like an ECM motor. Troubleshooting these is much more complex, but on pages 10.11, and 12 of this manual it walk you through some things to check. If you want to troubleshoot yourself, I recommend going through these checks.
Specifically a section : Motor will not start
Not seeing anything about the thermostat. But it does start out with checking all molex connections and checking the 5 amp fuse.
OK, well you need to go through all the checks they indicate to troubleshoot. This may take a while.
I have to leave for a bit, but will check back later.
