a 'ground' issue can certainly be the cause of these problems, all related to the 12v Chassis fuse panel, located in your driver side front compartment, mounted on the wall, with a black cover velcroed on it.... remove it and see if there are any 'red lights' showing issues with certain fuses.

All of the issues you mention have to do with 'after marker' installation of chassis-related items from the factory, not from Freightliner. This special 'fuse panel' is the source for all of these powered items. Thor send me a replacement fuse panel when I started having issues with several RELAYS showing a red light, possibly that they were'nt working properly, and a windshield wiper fuse that kept popping. It's only a few 'battery cable' connections to replace it.

You might want to check the main connections on this fuse panel and make sure all are tight and well seated.

If dealers can't help you, then either the factory service center in Wakarusa Indiana can, or possibly the Freightliner OASIS Service center in Gaffney, SC, where these chassis' are originally built - although it's not really 'their' build issue, but one from Thor's facility.

Trace the ground wire(s) and see what you can find. You may can do this yourself, if the fuse panel itself is not the issue.
