E88 problem with top and windows

[Juliane92]

Havent seen anyone talk about this and I’ve scavenged for days through fourms. Just bought a e88 with the windows not working at first they were getting no power changed the frm then they started to move as doors open and close the front windows work on protools and inpa but no buttons work not passanger or driver checked the window fuses checked for lose wiring in the door boot my mirrors still work and that still gets power. All my lights work as they should. I saw a e93 post that had the same symptoms with no solution dead thread. Any suggestions will help dont wanna go to the dealership.
