I have a 2003 chevy trailblazer and my "service 4wd" light came on about three weeks ago. My mechanic said he thinks it is a computer issue and I need to know what "exactly" the type of computer that controls that is. Computer mudual? Or whatever I have to get. I need to get this part asap.
have the same problem?
