My 94 S320 W140, express window up or down don't always work. I've tried resetting but again sometimes will reset, most of the time won't......frustrating. This is for all windows. Today it started raining during the drive , pussed the button for each window and they all worked. Turned the car off when I restarted the car and tried the windows the express would not work. Any Ideas.
Also noticed my windows don't close when locking with the remote. They used to, if left open and the remote lock was activated all open windows would close.
