Hi, I’m having an issue with my Hyundai sonata rear passenger window. The window rolls down as normal from both the passenger rear seat in the driver seat, as well as rows up from the passenger rear seat. However the window will not roll up from the driver seat… Any ideas on what this might be before I take it in?

 

The window motor test fine as do the switches at the door. (fuses and relays also okay)
The master switch does not work. So, must be either the master switch or the wiring??
