Are you sure you have all the ground wires grounded securely? Also on 535T drivers down is Green (motor side) & White (switch side). You really dont need this wire however since the JLU has auto down anyways... Almost seems like you wires are crossed. From 535T Driver Up should be Brown (switch side) & Blue (motor side). JLU wire is OG/GN I believe.Well ordered another 535 and it is doing the same thing. I have the big blue and small brown hooked to the green/orange down with off the switch. Brown to switch side, blue to motor side. Still will not let the window roll down on driver side. Work fine on passenger side. If I swap driver and passenger wiring, the driver will work but passenger will not. It is wired per the post. 18 JLUR. Any suggestions?
