Hello all. Just got my Fiat earlier this year and it had window issues from the start. I can't roll down the driver window or the rear passenger window but I can roll up the rear passenger window if it's rolled down locally. I've replaced the control module and the wiring harness which seemed to fix the driver window issue for a while but never fixed the rear passenger issue. So I went to replace the regulator. The one I got happened to be the wrong one but I am having trouble finding the correct one because everyone I come across only has a 2 pin connector while mine has a 6 pin connector.

Can someone tell me why I can't find a 6 pin regulator or where to find this one?

Any ideas as to why I can't roll down the rear right side window from the driver controls but I can roll it up?
