Hey, all,

I've recently noticed a come-and-go vibration from the passenger side of the dash of my '97 C230. It would happen when driving over a rough patch of concrete (and believe me, we have plenty of those in New Orleans). I thought it might be the cabin filter housing, since I've only got one clip on there (I lost the other behind the footwell panel), but everything is tight there. I tried popping out the dash speaker on that side, thinking it might be loose, but the sound continued.

So I checked my Haynes (UK) manual and found several bolts that hold the dash (facia, in UK parlance) in place. You pop off that plastic panel at the end of the dash, the panel which faces the door, and tighten that 8mm bolt. The panel clips right back on. Then I opened the panel under the glove box, the one you remove to change the cabin filter, and tightened 2 more bolts at each end.

To be sure, I snugged down the screws on the A/C vent, then put some thin insulating foam, the kind you buy at Home Depot to weatherstrip your house doors and windows, in under the speaker grille, and clipped it back into place.

Voila! No more vibration, at least for now! What a solid little car . . .
