I did have this frustrating issue, my remote worked but the switch did not.
Went through 3 switch's, the original WAS bad.....the 2nd & 3rd are good, figured that our after the discovery of the IN LINE fuse. In the Big Country this was located on one of the "red" wires in the battery compartment....it IS independent of the Remote feed.
Good luck!!
