I checked all the fuzes I could find, and didn't find any burned out. Is this a matter of a relay that might have a bad solder? (I had this problem with the windows recently, and a re-soldered connection made the problem go away.) If so, how to find the relay? Of....is it something worse, likely? Any ideas appreciated.

No check engine light? Speed sensor and computer effect cruise control. If the fuse is good you'll need to make sure all sensors are operational before condemning the module. Your brake lights must also be working, no bulbs burned out.

The cruise control on this model is vacuum controlled, you most likely have a cracked vacuum line or lines at the vacuum pump located inside the left front fender well area. I hope this helps.

Also check the brake light switch and if it is a manual trans it could be the clutch switch, good luck
