Harrumphs and gafaws. Make model and year would help. However, I just fought a similar battle. In my rig, the vacuum pump that allows you to direct dash air is on the same circuit, and same 15A fuse, as the Ignition Switch Overide, or ISO. The ISO does a few things, but most observable, it forces he steps to follow the door when you turn on the ignition.

Yes make model might have helped was just a little upset it is a 2003 pace arrow

Gas or diesel. Diesel engines make no vacuum so they usually have an electric vacuum pump. Gas engines create vacuum which is tapped off for other purposes.

Look for a fuse labeled ISO, possibly 15A. Se if it's blown.
