Eric, we bought a 1998 E320 new. Periodically there are electrical issues: windows will not operate, seats will not move. If you experience either of these problems simply pull the No. 16 fuse (in the main fuse box in front of the brake booster) for a minute, or so, with the engine running and reinstall the fuse. That resets things and seats/windows operate properly. Our local MB dealer's Service Department was unable to pinpoint the root cause of the problem so I perform that "remedy" every so often … sometimes it's every other week or so, sometimes less often … no rhyme or reason to frequency.
