The rear window would not go up unless you pressed the button 100 times. No problem going down. I opened up the relay box and found the relay had burnt through the connecter so deep it wasn't contacting it anymore. I scratched the burntness off, and bent the tab down just a hair so it would contact again. Window works flawlessly. This is not meant as a permanent fix but as a temp untill you can follow matt16 https://www.yotatech.com/forums/f116/rear-window...runner-137193/ and his walkthrough.
