One problem related to clutch has been reported for the 2003 Chevrolet Trailblazer. The most recently reported issues are listed below.
Fan clutch not working. I own a 2003 chevy Trailblazer LS. I have looked into this problem through the internet and there are so many complaints about this problem. This should be a recall because I can understand several but not in the hundreds. There is a bad tapping noise and it's from the fan clutch going bad. It's very expensive to repair this problem.
