Hi there I've got a 1999 w220 S500L & I love it. It's got a few gremlins as expected. Lol. I had to replace drivers door module as I could open any windows etc. After changing it everything now works except passenger side front seat & window don't work. Although the rear passengers controls do adjust the front seat. I can't open window from drivers door. I can hear something clucking. The mirror works ok & the actual control unit lights up. Would the issue be the passenger door module is faulty???
