Blower is not working regardless of switch speed position. Cannot find where (exactly) the blower motor fuses and relays are in the vehicle.

Good afternoon,

I attached the relay locations and the fuse locations to check.

If you have a test light, we can do some testing to find the failure.

The most common issue is the blower resistor on the heater blower box.
