Broke the mirror & electric windows switch hub!
Learnt a lesson - not to follow instructions blindly. There are some very useful resources here on the forum, thanks to all the members.
My window regulator has either dislodged or broken, and the window was stuck midway. Being the impatient me, I took the door panel apart with guidance from the forum, and didn't realise that mine is a 2007 147 and had a couple of additional screws - there was one holding the switch hub which I didn't notice in the dark, and I forced the hub out, which led to just the top part coming off (breaking). There were some small plastic pushrods inside which help the buttons push the points on the IC beneath. Most of them are lost, I managed to buy similar sized plastic screws on eBay, and can now make the mirror control round button work. But I have not managed to figure out what was beneath the window up/down buttons...can any one help?? I am not too far from fixing this and can save myself £50 on a used one!!
