I might suggest you check the salvage yards for a good , used " fuse box " , in case the origional continues to have problems . Worth having as a spare , if you can find one cheap enough .

The alternative is sometimes to wire in a remote relay . Eric O. of South Main Auto / YouTube did this on one of his videos .
