Dodgy Cruise Control Fix: Magnum Diesel Repair Advice

Had the same issue on my 2007 Dodge Charger Diesel. The cruise control symptoms matched exactly, dashboard light illuminating but no engagement. After diagnostic testing, it turned out the pedal switch under the brake pedal had failed, which is a common fault point for cruise control systems. The brake pedal switch serves as a safety cutoff for the cruise control, and when it malfunctions, the system stays disabled. The mechanic found damaged wiring at the connection point where the pedal switch connects to the main harness. The clock spring in the steering wheel was tested but worked fine. This was not a major repair in terms of complexity, but finding the exact fault point took some time with specialized diagnostic equipment. The fuse box was also checked as part of troubleshooting since blown fuses can cause similar symptoms. The fix involved replacing the complete pedal switch assembly and repairing the wiring connection. Post-repair testing showed all cruise control functions working normally again. The vehicle has run without issues for 40000km since the repair. Worth noting that leaving this issue unaddressed can lead to other electrical problems in the cruise control system over time.

Thanks for sharing your experience. Had almost identical symptoms with my Dodge Magnum last winter, cruise control light showing but completely unresponsive. The speed sensor and throttle position were both tested but ended up being fine. The brake pedal switch diagnosis matches what my mechanic found. Just wondering how much the final repair cost in your case? Also curious if youve noticed any other electrical quirks since the fix? Sometimes these cruise control issues can signal broader electrical problems, and Id like to budget accordingly if I need more extensive repairs down the line. The dashboard light still occasionally flickers on mine even after the initial fix, so Im monitoring that closely.

After seeing the mechanic for the cruise control issue, everything works perfectly now, no more flickering dashboard lights or unresponsive controls. The total repair came to 95€, which covered fixing a faulty cable connection at the clock spring assembly. Much simpler than expected. The cruise control system in these Dodge Chargers can be sensitive to wiring problems, but once properly fixed, they typically stay reliable. Since the repair six months ago, all electrical components including the brake lights and steering wheel controls have functioned normally. No additional electrical issues have emerged. For your flickering dashboard light, this could indicate a loose connection in the fuse box or related wiring. Worth having the mechanic check these specifically since intermittent electrical issues often point to connection problems rather than component failures. Based on my experience with these models, once the root cause is properly identified and fixed, you shouldnt need to budget for additional cruise control related repairs. The systems are generally robust when all connections are secure.

Finally got the cruise control fixed last week. Took it to a different mechanic who specializes in electrical issues. The speed sensor connections were fine, but they found a damaged wire near the brake pedal switch that was causing intermittent problems. The dashboard light stopped flickering after they repaired the connection. Total cost was 120€ for diagnostic work and repair, more reasonable than I expected. The mechanic also checked the fuse box connections while they had it apart, which gave me peace of mind about potential future issues. Quick 2-hour job and the cruise control now works perfectly. No more unusual dashboard light issues either. Pretty relieved it wasnt a major electrical problem like I initially feared. The thorough diagnostic approach at this shop definitely made a difference compared to my previous repair attempts. Good to know these issues are typically fixable without major component replacement. Thanks for helping me understand what to look for. Made me feel more confident pushing for a proper electrical diagnosis rather than just accepting the first uncertain repair quote.
