Sorry about multiple threads, just trying to get the car in order...

I got a smokin deal on a new to me '06 Malibu 3.5L. I am a tall, big guy and the interior room is the stuff of dreams, however the fabrics are dirty and need a good cleaning, and the former owner must have been a smoker because there is a cigarette (or 4/20 cigarette) burn on the passenger seat. I need to thoroughly clean, and repair the fabrics in this car before it grosses me out!

I suspect the burn will have to have the fabric panel replaced by a trim shop, but is there anything I can do aside from that to fix this?

What about the cleaning, what is the best thing to use to clean the interior fabrics?

 

Last one on the car for today. There is a weird buzzing noise that comes from the center of the dash that starts right at 50mph, and just buzzes away until just over 70mph.

Any idea how to start troublsheooting what could be in there driving me insane? I'd like to fix it and get a nice peaceful highway ride...
