I have a 1992 MB 300TE with 4matic. The 4matic yellow light does not go out, so I assume the 4matic is not working. I have had the module tested, it is OK. The transfer case is OK, as is everything else we've checked. Any ideas or suggestions?
You are going to need to scan it for trouble codes and go from there.[/Url]
