The relays have position markers under them. The high fan relay is in position "B"
Low fan is "C"
There will be the square relays on the left in pic.

The fuses are #7 for relay coils and fuse D for Power.

A quick test for fan circuits:
Key ON
Pull the connector off the blue coolant sensor at therm. housing..that should get HIGH fan

Jumper pigtail wire harness at a/c drier at end of pigtail. that will give you LOW fan.
Report those findings.
