rattling noise from cabin air filter?
No, its' not a snake. When I drive 70+ mph, especially in a headwind, I have a rattling sound coming from the passenger side dash area. I thought it was a bad fitting filter, but now that I'm on my third, different brands, I still have the noise. My wife's Cobalt does not. I keep forgetting to ask the service advisor(s), or my friend with a HHR, but here's my chance. I've searched the forum and not found a reference. My '04 Silverado makes a similar noise, but it's from the outside trim and a known problem (and fix), and not as frequent. But the HHR rattle sounds like it's internal. Anyone else have it?

I have checked all front (and rear) end pieces, hardware, and fasteners in the last two weeks while doing brakes , shocks, tires, wheels, and tow straps. Nothing amiss. I checked and changed wiper blades the previous week. Up to spec. I am thinking about removing the cabin air filter to see if there's a difference. Another thought... could it be the engine air filter assembly? I doubt it, since at lower road speeds, but at full throttle, there is no rattle. Also: just went out to check antenna. Tight!?!

You MIGHT have a reasonable idea with the air filter box. If I remember correctly a couple of owners had broken or lose brackets.
At higher speeds it make be pushed back and "resting" properly. You probably did this but I would check to assure everything is tight in that area on the passenger firewall.

I'm amazed at how many Plastic Push Pins are not tight as I go around looking under fender wheel wells etc. etc.
Many Plastic panels and such are just plain loose and some can create excess noise when bumped, hit a hard chuck hole or bump, or under high wind conditions ... like buffeting @ 60/70mph.

Those little push pins are so cheap that when I had the bumper off to change the headlight bulbs I just replaced all of them, no more rattles and things are nice and super tight. Sometimes I yearn for the days when things were fastened on with good old fashioned nuts and bolts.

check the TSBs
There is a known noise that comes from the passenger side of the dashboard. There is a technical service bulletin for this which includes fixes. Dealer fixed mine, among other rattles, for $600 of labor. Car had to go back (twice, at no additional cost) to redo fixes for two other rattles, but the dashboard one was fixed on the first try.
