Check the switch itself with an ohm meter to make sure it has good contact. And make sure your getting 12volts to the switch.

 

Hi.

Uhhhh, that's a heck of a lot of choices thar, bud. I cain't decide which one to pick



How exactly did you check the fuses, with a meter to the test pins on the back, or just by looking?

Good luck!
