Window safety not available - help please.
Just started getting the "window safety not available" message on my Brera. Happened first time yesterday - passengers window dropped a couple of inches when my wife got out of the car and wouldn't go back up. Noticed the error message and reset the windows and it seemed OK, but got in the car this afternoon and message was there again. I've reset it again, but I'm assuming something will need replacing. I've read the posts on here and it looks like either the regulator or the control unit. Anyone able to point me towards the most likely culprit? Also, how easy are these to replace? I suspect there's a guide on here somewhere for taking the door panel off, but can someone tell me where the control unit is - and would that need programming if I replace it?
