My car is making a squeaking sound that is driving me nuts like fingernails on a chalkboard. It's got me to the point where I'm all tensed up waiting for the next squeaks. It sounds like when you move the rear headrests up and down, except I lubed my headrests so I know that's not it. I can't pinpoint it as it sounds like it's coming from all around me. I saw one post where squeaking was coming from the glass roof. Any suggestions on where to focus? It's been squeaking since July, but my service appointment has been moved back twice by one month each, so I'm scheduled to go in at the end of October now to have it looked at.
