2008 diesel super duty 250 crew cab. Cruise control not working. Went to Auto Zone, had batteries & charging system checked. Batteries fine. Alternator ok. Voltage Regulator failed.
Ford Dealer said must replace alternator as voltage regulator is now inside alternator. Diagnosed cruise control problem as brake switch. $768 later, have new alternator. Dealer said they misdiagnosed cruise control problem, replaced brake switch at no charge anyway. Told I need to replace "Power Control Module" as that was the problem leading to other problems
Part cost - $668. Did not replace "power control module" yet as tech said it would probably be ok. I am NOT familiar with new vehicles. My first diesel. Have had the truck since new. 67000 miles on it. All parts have been dealer installed since new. All service done by Ford dealers. Truck mostly used for camper hauling, including 10,600 mile trip to Alaska. Never been "hot-rodded", used for off-road play, or otherwise ridden hard.
Replaced idlers and belt March 15 to get rid of "chirping noise". What would you do ?
