JIM4391 Report post Posted April 2, 2012 Had my 2012 MH worked on recently for a dash air issue. It was fixed but now the exhaust brake and cruise control does not work. How can a rookie check this out? Share this post Link to post Share on other sites
wolfe10 Report post Posted April 2, 2012 Welcome to the FMCA Forum. Suggest you check with your chassis maker for what these two systems have in common. Most diesels use air pressure, not vacuum to actuate the exhaust brake. Most new diesels use electronic control for cruise control. Most likely common point is a FUSE. So, look in your 12 VDC fuse panel for the chassis. Brett Share this post Link to post Share on other sites
five Report post Posted April 2, 2012 You don't say what brand of MH you have. On my AC, I have 12v fuse panels scattered around in at least four different places. Share this post Link to post Share on other sites
