Replacement Drive Window Switch

Hi All,

My previous driver window switches had become corroded, I initially cleaned them to get them back to life but over time the damage went beyond repair. I purchased replacement part: 1Z0959858B. Upon fitting the part the switches were not working, what I did notice is that the window-locking button in the middle of the panel illuminates, and becomes brighter when you lift/press one of the window switches, and becomes brighter further when you go to the one touch raise/drop. From what I read they don't require coding.

Would be grateful for any advice on this :-)

Thanks
