Windshied vibrations?

[PaulV]

I am new at Rv ing and have purchasex a 2011 Istasca Sunova ClassA.
I get a nasty vibration sound when I hit about 50 miles per hour. Can't figure out if kt's the wipers vibrating or something else. Anyone else have this experience and how did you resolve the problem? Any help appreciated.

Don't have the same coach as you but had a vibration/fluttering sound going down the highway. Turned out to be a loose outside pillar cover that vibrated. One of the 3 screws holding it had come out. Made a heck of a noise. It was one of the covers at the ends of the windshield.

Welcome to the forum.

There are several threads discussing a high-pitched, resonance type vibration that is caused by the metal tubes in the front grills of some moho's. You can use the search engine near the top of the page to find those threads.

Best way to eliminate that as a cause is to simply remove the grill and hit the road for a test drive. If the vibration goes away, then you have to dampen the metal rods in the grill to prevent the vibration. If the vibration does not go away, keep eliminating one item at a time until you figure it out. You may search the Winnebago forum for solutions, also. Let everybody know how you solve the problem, that is what this site is all about.

When you hear the noise again, touch your drivers side window. If it's a slider, the sliding pane may be the source of the noise. Either the anti rattle clips are missing or the glass is vibrating against the screen. I have the same noise on my 2015 Coachmen. Your window may be made by Hehr. Do a Google search on Hehr anti rattle clips and Hehr window rattles.
