problem #1

Mar 102007

Silverado 3500 4WD 8-cyl Diesel

  • Automatic transmission
  • 2,610 miles
"service 4WD" error code shows up on dash display when driving through mud and water puddles, the vehicle enters 4WD before entering the mud/water but goes back to 2wd after being in the mud/water for a minute or two, also the 4WD push button light flashes when code is showing. After letting the vehicle dry out, the "service 4WD" error message does not appear. I need the 4WD all the time in the mud, not when it feels like working.
