The Cruise Control on my 2006 Sprinter 3500 isn't working - there is no response when I actuate the switch. After searching the forums, it sounds like people sometimes run into CC issues with brake lights or the pedal brake switch causing intermittent failures, but my brake lights are good, and the pedal switch seems to be actuating fine as well (the CC also isn't intermittent - it just never works).
I've brought it into a mechanic who plugged the diagnostic computer in, and said the ECU was coded for cruise control, but wasn't showing any response at all to the CC stalk. We tried replacing the lever unit, but that didn't fix the problem. The shop thought the only other solution was a full ECU replacement, which is too expensive to be worth it.
Anyone have any other ideas for what might be causing this or ways to troubleshoot? It'd be really nice to have cruise control back!
