Thanks for the responce. I followed your instructions and it didn't appear as though any smoke was being sucked with any force. As I was doing this I noticed a regularly intermittant humming noise coming from the area of the trunk. It sounded like an electric motor (similar to the sound the power windows would make) that engaged for one second then quit for one second and repeated for as long as the key was turned on.
I tracked it down and discovered the source was behind the thin wall of the trunk on the passenger side, wrapped generously in foam padding. It's definately the source of the noise because every time it engages the whole unit twitches in your hand. There are two sets of electrical wires and a couple of vacuum lines running to (or out) of it. It's black with a grey cover, about 2 inches wide x 5 inches long x 4 inches deep. It's part# is 202 2800 12 48, but the parts store doesn't recognize the number.
Do you know what this is? Is it behaving as it's supposed to?
Thanks, Bob
