Please help anyone!

Got a Tein Coilover installed with EDFC on my 2017 IS350 RWD. After the installation my Right side mirror wouldn't function anymore, it doesn't respond to any of the buttons and does not auto fold as well. also the the memory seat buttons are not working, also noticed that the seat doesnt push back anymore when you turn off the car. but the controls of the seat does work including the steering if you adjust it manually.

The installer for the tein controller at the trunk i remember was trying to find a live wire on the Left hand side but couldnt find one. Was thinking this could be were the problem started when they were doing something with the wires at the back, not sure.

Called the dealership and they said something may have gone wrong with the body ECU but will need to bring in the car to get diagnosed.

Was hoping that anyone here might know of a fix.

Thank You!
