The aspirator in the headliner (the one in the rear, not the one over the driver's seat) is buzzing like a bee in a plastic cup. It's really annoying. The front aspirator was easy to replace then it was buzzing, but for the sake of my sanity, I can find no way to access and replace the rear aspirator short of spending hours removing the whole headliner. The GMC service manager told me it involves upwards of 12 hours of labor charges to do the job and I told him go fly up a tree with that. Is there an easy way to get at it without gutting my interior like a fish?

Never had to get to mine yet so I can’t give any advice on easy replacement, but might try and get a can of compressed air and see if you can blow out any dust or debris that might be in there and see if that helps.
