Angry How to troubleshoot dead cruise control?

D4mnit, going on a 2800 mile roadtrip in three days, and I find that my cruise control isn't working tonight. It was too dark outside to really look at anything in detail

I did confirm the cruise control cable was attached to the TB, but the cable has literally no free play in it.

Anyone know which fuse controls CC? I just had the master cylinder/clutch/tranny rebuilt and will wait if it's the CC control box...but if it's something as simple as a fuse or crimped cable, I want this to work for the trip!

Did you check to make sure you don't have a brake light out? The CC circuit uses the break light assembly wiring.

Check it and lemme know

Brake lights are OK, and the CC fuse is shared with the A/C relay...and the A/C works...

Think I found it. There is a white cylindrical switch which gets depressed when the clutch pedal is at the top of it's travel. However, at the top of my current pedal's travel, it's merely resting on the top of that switch, and not depressing it.

With the clutch pedal in, that switch is spring-loaded. I presume it's just a matter of tweaking the position of that switch closer to the pedal? I wonder how far that switch needs to depressed for the CC system to consider the clutch pedal out?

OK, disconnected the electrical clip, then rotated the threaded part of this switch clockwise until the square edge caught and locked. That fully depressed the switch with the pedal out. Wonder if this what was causing my intermittent CC cutout on previous roadtrips?

Will test tomorrow as I'll have to park in BFE if someone grabs my spot.

You found it. That switch above the clutch pedal is there to turn the cruise control off if you press the clutch... same way pressing the brake will disable the cruise. Your adjustment should fix it.
