Strange one. At times when starting when cold the '04 DS11, the roof glass will open on it's on, sometimes only one of them will open, sometimes both of them. If they don't, I can hear a sound from them as if a connection is being made but they don't open. Has anyone had this and can tell me where to start ?

 

Yeah, mine does this. Most times when power is sent to the module, the motors move a bit. Usually the rear, but sometimes the front also. I cut into the power going to the unit and installed a latching push button so they don't do anything until I turn them "on".
