Cruise control
Is there a common problem with the cruise control system on these trucks? mine is a 94 5.0. my horn / cruise didnt work so i replaced the clock spring. now the horn works, but not the cruise. then i replaced the pressure sensor on the master cylinder. still doesnt work. any ideas? i can hear the Relay click when i push the Cruise buttons .

This should help you narrow down the root cause: 1983 Ford Bronco Diagrams picture | SuperMotors.net
If all the inputs are good into the speed control servo, the servo is most likely bad. Very common failure.

thread resurrection
New here and hope you can help me figure this out.
1994 Bronco Eddie Bauer 302/E4OD
The other day I replaced the TP and EVP sensors and now the cruise control doesn't work.
The truck runs better now but I'm stumped. All the fuses are good at the power distribution box and the inside fuse box, I checked the 5 cruise control switches for power and get different voltages out depending on what switch is pressed.
Two things - I don't get power at the servo but I'm not really sure what voltages i am supposed to get and on which wire and I used to get a click inside the truck when the set button was pressed but now there is nothing. Where is the relay that The Gageinator mentioned? is there any other control module in the system or is it only the one in the servo?
