Fuse # 7 (40A) is the blower motor fuse.
You can swap the blower motor relay (in the fuse box) with another identical relay to see if that gets it working [if so, replace the relay].
If they are good, with the key on and the blower motor switch on; check for power [12v] at the BRN/RED wire at the blower motor connector. Check the BLACK wire also; it is the ground wire.
If not power is there, yet the fuse and relay are good (on vehicles with automatic climate control), check for power on the RED wire at the blower motor module/resistor. It is located on the blower motor housing under the passenger side dash, behind the glove box area and is held in by three or four phillips screws.
If you have power there but none reaching the blower motor, remove the module/resistor for further testing using an ohmmeter. (Let me know if you need steps on how to do this.
The windshield wiper is circuit breaker 1 (20A). Swap that relay as well to see if that cures the problem. If so, replace the relay.
Check the radio fuse.
