Hello, did some searching and couldn't find a related issue. If i missed it, please send my way! 2003 Eddie Bauer, and the panel vents will fade in and out, and almost switch for no apparent reason. Had the same thing in my 2003 Marauder, and there are rings near/on the vacuum lines that were worn, replaced and cleared up the issue. Same thing with the Expeditions? Thanks in advance for any insight!
