I have a truck that had the cruise control disabled. I'm trying to enable it. The connection in the steering wheel is connected. I've checked the owners manual to se which fuse it might be, but I don't know which one it may be. It also may have been disconnected under the hood.
Do you
have the same problem?

Cruise control systems can be disabled for various reasons. Since you mentioned checking connections in the steering wheel and fuses, let's focus on some other possibilities. However, it's essential to keep in mind that troubleshooting issues like this can be complex, and if the problem persists, you should consider taking your vehicle to a professional mechanic.

Here are some things to check:

Brake Pedal Switch: Cruise control systems are designed to disengage when you press the brake pedal. If the brake pedal switch is faulty, the system might think the brakes are being applied, and the cruise control won't engage. Check this switch to make sure it's functioning correctly.

Speed Sensor: The vehicle speed sensor provides speed data to the cruise control system. If this sensor is malfunctioning, it could prevent the cruise control from working.

Clutch Pedal Switch (if manual transmission): Like the brake pedal, depressing the clutch pedal should also disengage the cruise control. If this switch is faulty, it might prevent the cruise control from engaging.

Under the Hood: There might be a vacuum line to the cruise control module under the hood that has become disconnected or is leaking. Check for any disconnected hoses and listen for a hissing sound that might indicate a vacuum leak.

Fuses and Relays: The cruise control system on a 2006 Ford F-350 relies on fuses and relays. While the owner's manual might not specifically list a "cruise control" fuse, related systems (like "engine control, " "instrument cluster, " or similar) could be involved. Check all related fuses and relays.

Steering Wheel Controls: Even though the connections are intact, the controls themselves might be faulty. They can be tested with an ohmmeter to ensure they're working correctly.

Check Engine Light or Fault Codes: If your check engine light is on, or there are fault codes stored in the vehicle's computer, this could prevent the cruise control from engaging. Use an OBD-II scanner to check for any fault codes.

Cruise Control Module: If all else fails, the problem might lie within the cruise control module itself. This is a more complex issue that typically requires professional attention.
