My brake lights stopped working. I have replaced the bulbs, circuit boards behind the lights, fuses and the brake light switch. I cannot figure out what to do next.

Hello,

It sounds like it is the turn signal light switch, here is a wiring diagram (below) and a guide to help you get started.

Please let us know what happens, we are interested to see what it is.

Cheers, Ken

It isn't the turn lights. When I push the brake light switch as far back as I can it turns off and the stop fuse keeps blowing

I would start at the brake light bulbs, remove them to see if the fuse blows

Please let us know what happens.

Cheers, Ken
