3rd Gen rear wiring umbilical

Today I soldered the blue/white wire in the rear window umbilical. The wire was broken due to years of opening and closing and this wire took out remote key use, power back window, wiper and washer spray.
I wonder if there is any way to replace this wiring bundel internally without extreme cost?

 

Unfortunately super common. It’s best to get new wire and splice them in. Here’s a tutorial if you’re interested

Thanks for the video tip! I got a few good techniques and have made a few of the repairs! Very helpful
