Drivers side power mirror/window not working

[AndreKK]

Hi everyone. 2012 Cherokee KK. some of the functions on the power control unit on the drivers side stopped working. The mirrors doesn't fold or adjust, the front windows doesn't work neither the door lock/unlock function. I can still wind the back windows up and down. Checked fuse M26 and M30, both good. I replaced the complete power mirror/window/door lock unit with a new but still the same. Any advise from here on forward will be appreciated.
