06' 525 - When you press and hold the unlock button on the key FOB, all windows / sunroof open except the passenger rear window. Is this correct?

The switch on the drivers door and on the rear passenger door open the rear passenger door window in increments, ie pull the switch, goes down 4", pull again, another 4". Is this correct?

If this is true of the passenger rear window, why?

 

Doesn't sound right to me. Been a while since I've put the rear windows down (usually have two small kids back there) but I seem to recall all four working in a similar fashion. Pull the switch once, release and the window moves all the way down. Pull and hold for the desired time and the window will go down until you let go. Same in reverse for closing. Only time I've ever seen the key used to open all windows was at the dealer when I took delivery and I recall all four going down all the way. Sounds like you've got a malfunctioning window back there...

 

All windows should lower if you hold the unlock button on the key fob...

 

Yep. You sure have a malfunction there!

 

Think I got it. Seemed to only do it when the window lock on the drivers door was activated. I'll try again tomorrow to ensure it wasn't a fluke.
