94 F150 Cruise Control
My Cruise Control on my 94 F150 doesn't work. I checked the various voltages at the servo and all were okay except from the Vehicle speed sensor. The speedometer and th odometer both work fine. I can only find one VSS on the tranny. Does anyone know where I should go next to solve this problem?

The clock sping in my steering wheel went bad and coused this problem on a 94 I had before. The things that Van mentioned would be other indicators of this as well. I replaced the cruise control unit before I linked the problem with my air bag light bieng on. I know on the manual transmission trucks the VSS is in the diff and I believe the autos are the same. I dont believe your speedo would be working if this had gone out. Just some thoughts.

If you checked the all of the various voltages at the servo that are shown in the Helm's service manual you do not need to check the clock spring. If the clock spring were broke you woulnd't get correct readings at the servo.
When you say you checked the various voltages and all were correct except the VSS. Do you mean you checked the VSS and it wasn't correct or you didn't do that check because it was difficult? It would have involved either jacking up the rear wheels and running the vehicle at about 30mph or hooking up a meter and driving the truck at about 30 mph. By the way the VSS signal is an AC voltage.

Thanks kioot. I checked the VSS voltage at the servo connector with the rear wheels off the ground at about 30 MPH. Now that you mention it, I cannot swear that I had the DVOM on AC volts, it may have been on DC volts. I might have to recheck that. All that volt readings I did were at the servo connector.
