Check the speed sensor. Look up the location at autozone .com or google. It is either near the tranny or at the passenger side wheel. The speed sensor is almost always connected to cruise control problems.

FROM LUSTY KID:
Check your bulbs first, I have lost both headlights on my ford at once on account of the bulbs burning out at the same time. Same thing probably happen, you have one filament out. The lights can work, but if the filament for brake is burnt, you don't see brake lights.
As for the cruise control. Check fuse box first. If OK check vacuum hose to actuator in engine compartment for starters.

normally the brake switch is the issue with these trucks. it is located under the dash where the brake pedal meets the linkage to the brake booster.

May want to look at replacing the wiper circuit board.It is located on the firewall adjacent to the wiper motor and has a some what square black cover with 3 torx screws and wireing harness pluged into the side.We had a truck that every time you washed it the wipers would stay on until it dryed out.You can try removing it and spaying it down with contact cleaner just watch the brease on the two contact tips.Well hope this helps.
