Windows don't auto-roll up when closing top
I have a 2011 SL550. Top works great. When opening top, windows go down fully as they should, however, when I go to close the top the windows will not roll up (neither rear or front). I've held the center button down for a minute plus and no dice. Reset all the windows and still nothing. I can roll the windows up manually with no issues. The only windows that do not auto-up are the rear qtr windows (not sure if that's normal or not, as they auto-down). Only current code I'm getting is a possible faulty passenger SAM unit, but not sure if related. . Any idea on what this could be or tips on trouble shooting? Thanks

Do they do the short drop when you open the door and then go back up when you close it? Do you get the 'Hardtop Closed' message on the dash?

Yes, both side short drop as they should. I do not get a "hardtop closed" or "hardtop open" message. While holding it down it will say "hardtop in operation" then disappear once it's fully closed/open.

My 2007 DID the standard as designed process you described until I bought this mod. You can set up windows and top functions to take care of the issue. You can put top up down while underway and fully open and close with your standard key fob.

I don't know about the 03 or software updates for that. I bought the Mod for the Open/Close and lock features from std key fob and to operate while underway, the better design of window up/down came with it. My wife likes the top down and all 4 windows up (not 2 as standard) and roll bar up. Better hair day that way. Meanwhile, I like top down all windows down. EZ to do with how I set up Mod.

The feature that drops the windows a couple of inches when you open a door makes perfect sense because they then go back up automatically to seal against the top. HOWEVER if the top is down and you start to raise it, the windows go down a lot more and don't go back up automatically. This would be OK except that the windows now have to be raised manually which requires the ignition being turned on and you need the key with you. I find this quite irritating because this often happens to me when I have left the key in the house and rain is threatening! I wonder why the windows don't go up automatically in both cases. Am I missing something?
OR you can get a SmartTop and control the roof/windows from the comfort of your home

I think the automatic window closing was discontinued after a couple of beheadings and limb amputations.

In the diagnostic aid document, stage 5 of the closing sequence reads: "all windows are closed". When windows remain stuck in the short stroke position, either a tubular frame lock switch or a front lock switch (there are two of each) is failing. If a window stays open altogether, something else is wrong.
