Cruise control light comes on when you hit the on switch but it will not engage. on 1996 Dodge Ram Van 3500

The cruise control will not set or resume. While driving at any speed, i can push the cruise on/off switch and see the light come on indicating it is active, however, when i push the set button it will not engage. Need to know where to start looking to fix it and if possible, a schematic would be great!

agree with goodguy or poss bad brk light switch
Gotcha I will check the fuses first. If the fuses are fine, where can i locate both the brake light switch or cruise control module? Also, my brake lights work fine so is it possible that the switch is still bad?
on brk pedal assm
Gotcha. Is it still possible for it to be bad even though my brake lights function the way they're supposed to?
