Window issues after recall re blower-regulator wiring harness.

[naregf]

Took my 128i in to BMW for a recall re blower-regulator wiring harness. They got it all fixed thankfully. The thing works like a charm.

However, got car back and windows were behaving strangely the moment I picked it up.

1. Auto close function no longer works.

2. Slightly worse is that the automatic up/down that occurs as you shut the door also does not work – the window stays outside of the door frame unless you delicately force it under the frame every time.

Perhaps noteworthy is that my trip meter was also reset when I got the car back and that this issue is happening with both windows.

Anyone else with similar issues? Any thoughts on what may have occurred / how to fix it? My best guess so far is that the windows need to be reinitialized, and this may have occurred due to a power loss. Any other theories?

BMW dealership is denying all responsibility in the matter: "the windows are not related to blower-regulator wiring harness". BMW Canada and BMW dealership both say the repair will be covered if it is related to work that was done during the recall. BMW dealership still wants to charge full rate for a diagnostic

Sounds like they disconnected your battery. The steps to reactivate the auto down power windows should be in the owners manual. If memory serves you just press and hold the window down buttons for 10 seconds. HTH

Thanks for the heads up. I also believe battery was disconnected, but can't tell for sure.

I tried this and a bunch of other methods people recommended throughout forums.

Not sure what's causing this, but I'm still at a point where auto-down always works, auto-up never works, and the drop when you open/close the door never works.

If the door is open and I hold the switch to roll the window up, it hits the upper limit, makes a weird noise (like a rattle, I feel the door shake a bit, and like glass hit metal) and if I hold it longer it rolls back down by itself while I'm holding the switch up. At a loss fo what is causing all this.

Note that when using the key to open / close windows, the sunroof works, but the windows won't open or close.

Edit: tried various other procedures again, some on different forums, and had other people try it too. I also timed some of them to make sure I was hitting the timings. NOTHING changes.

Edit 2: tried disconnecting and reconnecting battery – no improvement.
