Clean the fuses and fuse holders.

Unplug / replug the relays at and near the fuse box.

Swap around the identical relays at the fuse box (horn relay can usually be used).

(Make sure the relays swapped are identical!)

Might also be the trip computer/alarm. Try disconnecting the negative battery cable and re-connecting it to reset it. It can be bypassed if necessary (check the internet as to how)
