Peugeot 207 Cruise Control Issue

Sounds frustrating! The cruise control system in your 207 is like a chain. Have you noticed if your brake lights are working correctly? A faulty brake light switch can sometimes disable the cruise control. Also, does the dashboard light up when you try to engage the cruise control?

Brake lights work. No indicator light on the dashboard when I try to engage cruise control. Does this point to the steering wheel assembly, like the clock spring or a plug connection? Or should I look at other causes?

Given no light appears and you've checked fuses and brake lights, it points to the steering wheel controls or the clock spring. It's also possible a cable or plug connection is defective. Diagnosing that without tools can be tricky. It might be wise to visit a workshop. They can pinpoint the problem with diagnostic equipment. Repair cost will be around 95€.

Thanks for the help. I'll schedule a workshop appointment to diagnose the issue. It turned out to be a defective cable connection, as you suspected. Thanks for your time.
