Hi All-
New to the forum and new to a Chevy Blazer. Just picked up a 1998 Blazer LT the other day. Runs great and everything, but I noticed the other day when I was sitting inside the vehicle in park, I could hear this strange rattling/ticking/clicking sound coming from the driver's side area, near the roof. Took a while to figure out where it was coming from, not sure 100%, but any how, it seems to be coming from this speaker-like device mounted in the roof above my head. It almost looks like a tweeter, but it is only on the drivers side. The sound has no bearing on the stereo or speaker balance, and the thing looks like it is a factory-installed device (matches color and paneling wise). Any idea on what this may be, a hands-free device? Also, any idea on the ticking sound coming from it? Thanks for all of the suggestions and help.

Really shouldnt be anything above your head in the drivers seat other than like wires running to rear. There is a tweeter in the drivers side dash it may be echoing and seems like its the roof, but it should react to speaker fade and balance adjustments. My only idea may be that its like the roof rack rattling, does it seem to be tight to the roof?

That's the wierd thing, it is some sort of speaker-like device only on the driver side. I wish I could figure out what it is. It is about 2" in diameter, right next to the handle mounted on the interior of the ceiling. Also looks like it belongs there and is may be some aftermarket thing, since it matches the interior color and plastic. Thought it might be a hands-free phone thing, but not sure. Can't find anything in the manual. I will check the roof rack, but if I put my palm over the speaker-like device, it seems to muffle the sound some. I don't think it is a huge problem, but it is annoying. You can distinctly hear it with the radio off and at an idle, not while driving (too many other sounds then).

You probably have the Auto Climate Control correct. If so, that is the interior temperature sensor. It has a small fan in it to draw air through it for sensing the temperature to make the appropriate adjustments per the set point.
