Cruise Control Troubleshooting

[MRP78]

I swear my cruise control worked last time I checked, but today it didn't. Master switch on, hit the button on the end of the turn signal and nothing. Everything looks hooked up. Where do I start?

Brake switches, one is vacuum cutout, and one is electrical, if the switch slides out of the bracket a bit it won't engage the cruise, cruise box will think the brake pedal is pushed.

Visual inspection of vac lines, electrical and then as stated the brake switch adjustment, which is a sliding ratcheting adjustment done with pedal apply.
