High and low beam fuses operates both sides respectively and since at least one position is working, it is not the fault of the fuses.
You have a break in the wiring circuit between the right and left headlamps, one for the high beam and the other for the low beam.
Check the connectors for forward light harness, about 75 cm from horn connector. Wire color is Dark/Blue. It is for the low beam lights.
Use a fuses jumper to ground the Dark/Blue wire of leaft low to test if the low beam comes on for the left side. Grounding the Pink ( or Orange) wire would turn the high beams on.
Repeat above at right side headlamp.
The other connector for the high beam is at engine harness, left rear of engine.
Check for corrosion at connecter terminals. Corrosion of terminals would result in a break in the circuit.
A test lamp to test for voltage or a DVOM to test continuity would help.
Unplug both head light connectors and test for continuity between above described wires would enable you to understand if there is a break between them.
