I have a 2006 300C and the drivers side auto up is not working, the auto down works but not up. This has happened before but has goneaway in a day or two. I have also had problems with the rear drivers side window not working. One time the auto locks would not lock upon reaching 15mph and would not lock when pressing the lock button. I have never had a car with these kind of electrical issues, can anyone offer some advice?

the first thing you need to know is that ALL power window wiringgoes through the drivers side switchfirst. are you sure it should have auto up, i have only seen auto down.

 

You can reset the express feature by pressing and holding the down button, and when the window reaches the bottom, hold to the count of ten, then return the window to the top bypressing and holding, andagain hold for the count to ten when the window reaches the top.

Hope this helps
