klparker Report post Posted December 1, 2022 Have 2001 Itasca Horizon, diesel. Air pressure and fuel gauge have stopped working. Can anyone tell me where to find the VDC. I switched gauge connectors (back pressure to front) and the gauge still didn't work. Share this post Link to post Share on other sites
