HVAC Blower not working!!!

My blower motor is not working.Is there a common failure on these ?
I have the schematic and it looks like its poss going to be a lengthy trouble shoot .
Does anybody know some common failure to look for 1st.

Checked fuses!!!!

Instead of checking all the wiring, take your glove box lid off and unbolt it and slap a new one in there. The motors do fail over time.

Or unplug it, check the harness for 12v. and then repeat the above step. If its the head unit, just swap in a used one.

I had a blower motor fail last year. I was on the highway and the thing was working fine, and then it stopped just like turning off a switch. Luckily, they're easy to change after you drop the glove box door down.

But just as a double check, grab a test light and see if there's power at the motor connection first.
